本发明是一种电源供应设备及其控制方法,尤指一种具有电子断路器的电源供应设备及其控制方法。The present invention relates to a power supply device and a control method thereof, in particular to a power supply device with an electronic circuit breaker and a control method thereof.
背景技术Background technique
现代人家中会有许多的电器设备,而电器设备一般而言,皆会具有一电线,让电器设备能通过电线电连接至插座,以接收市电电能而正常运作。此外,当电器设备为可移动式的时候,为了方便使用者使用,会直接在可移动式的电器设备中设置电池,让电器设备能直接接收电池电能而正常运作,藉此摆脱电线的限制,方便使用者移动。而当电池的电力被消耗完毕时,使用者就必须对电器设备进行充电,方便下一次的使用。There are many electrical equipments in modern people's homes. Generally speaking, electrical equipments have a wire, so that the electrical equipment can be electrically connected to the socket through the wire, so as to receive electricity from the mains and operate normally. In addition, when the electrical equipment is mobile, in order to facilitate the use of the user, a battery will be directly installed in the mobile electrical equipment, so that the electrical equipment can directly receive battery power and operate normally, thereby getting rid of the limitation of wires. It is convenient for users to move. When the power of the battery is exhausted, the user must charge the electrical equipment for the convenience of the next use.
较常用的充电方式,是通过设置一充电设备,并将充电设备设置于定位后,将充电设备通过电线电连接至插座接收电能,且充电设备设置有一组第一充电电极。当电器设备中的电池没电时,使用者便可直接将电器设备放置于充电设备上,藉此将电器设备上的一组第二充电电极与充电设备上的该组第一充电电极接触,让电器设备中的电池能通过该组第一充电电极电连接至该充电设备,进行充电。A more commonly used charging method is to set a charging device, and after the charging device is positioned at a location, the charging device is electrically connected to a socket through a wire to receive electric energy, and the charging device is provided with a set of first charging electrodes. When the battery in the electrical equipment is dead, the user can directly place the electrical equipment on the charging equipment, thereby contacting a group of second charging electrodes on the electrical equipment with the group of first charging electrodes on the charging equipment, The battery in the electrical device can be electrically connected to the charging device through the group of first charging electrodes for charging.
前述电器设备若以扫地机为例,为方便扫地机自行移向充电设备并构成电接触,充电设备的该组第一充电电极在设置上必须外露在外壳外面,才能够与电器设备的该组第二充电电极接触。但是,当充电设备的该组第一充电电极外露在外壳外面时,就容易被使用者误触而导致使用者被电击。因此现有的充电设备势必要进行改良。If the aforementioned electrical equipment takes the sweeper as an example, in order to facilitate the sweeper to move to the charging equipment and form electrical contact, the set of first charging electrodes of the charging equipment must be exposed outside the casing in order to be able to connect with the set of electrical equipment. The second charging electrode contacts. However, when the set of first charging electrodes of the charging device is exposed outside the casing, it is easy to be accidentally touched by the user, resulting in an electric shock to the user. Therefore, the existing charging equipment is bound to be improved.
发明内容SUMMARY OF THE INVENTION
有鉴于现有的充电设备其充电电极外露,容易被用者误触而导致使用者被电击的危险,本发明提出一种具有电子断路器的电源供应设备及其控制方法,在未对电器设备进行充电时,关闭电极上的电源,避免使用者误触的危险。Considering that the charging electrodes of the existing charging equipment are exposed, it is easy to be mistakenly touched by the user and the user is shocked by the danger.

有关于本发明具有电子断路器的电源供应设备的运作方式,详如下述。The details of the operation of the power supply device with the electronic circuit breaker of the present invention are as follows.
当该电器设备未电连接至该电源输出端Vout进行充电时,该处理单元121执行该待机状态,且该第二电压输出端OUT2输出的一第二电压通过该第三分压电路125产生一分压提供该电源输出端Vout。When the electrical device is not electrically connected to the power output terminal V out for charging, the processing unit 121 executes the standby state, and a second voltage output from the second voltage output terminal OUT2 is generated by the third voltage divider circuit 125 A voltage divider provides the power output V out .
而当该电器设备电连接在该电源输出端Vout与该接地端GND之间进行充电时,由于该电器设备与该第三分压电路125并联,因此该第二电压输出端OUT2输出的第二电压通过该第三分压电路125产生提供该电源输出端Vout的分压下降。也就是说,此时该电源输出端Vout的电压值下降而小于该启动临界值,使该处理单元121产生该启动信号自该第一输出端O/P1输出至该第一晶体管Q1的栅极。When the electrical equipment is electrically connected between the power output terminal V out and the ground terminal GND for charging, since the electrical equipment is connected in parallel with the third voltage dividing circuit 125 , the first voltage output by the second voltage output terminal OUT2 The two voltages are generated by the third voltage divider circuit 125 to provide the divided voltage drop of the power output terminal V out . That is to say, at this time, the voltage value of the power output terminal Vout drops and is smaller than the start-up threshold, so that the processing unit 121 generates the start-up signal from the first output terminal O/P1 to the output of the first transistor Q1. gate.
由于该第一晶体管Q1的栅极接收到该启动信号,该第一晶体管Q1进入导通状态,使该第二晶体管Q2的基极接地,让该第二晶体管Q2导通,并进一步使该第三晶体管Q3的基极连接至该第一电压输出端OUT1,让该第三晶体管Q3导通,且进一步使该第四晶体管Q4的栅极至该第一电压输出端OUT1,让该第四晶体管Q4导通。Since the gate of the first transistor Q1 receives the start-up signal, the first transistor Q1 enters a conducting state, the base of the second transistor Q2 is grounded, the second transistor Q2 is turned on, and The base of the third transistor Q3 is further connected to the first voltage output terminal OUT1, the third transistor Q3 is turned on, and the gate of the fourth transistor Q4 is further connected to the first voltage output terminal OUT1, so that the fourth transistor Q4 is turned on.
详细来说,当该第三晶体管Q3导通时,该第一电压输出端OUT1通过该第一电阻R1及该第三分压电路125电连接至该接地端GND而形成回路,产生电流。因此该第四晶体管Q4的栅极与源极间通过该第一电阻R1产生压差,进而使该第四晶体管Q4的漏极与源极导通,令该第二电压输出端OUT2输出的第二电压能够通过该第四晶体管Q4输出至该电源输出端Vout,进而对电连接在该电源输出端Vout的电器设备30进行充电。In detail, when the third transistor Q3 is turned on, the first voltage output terminal OUT1 is electrically connected to the ground terminal GND through the first resistor R1 and the third voltage dividing circuit 125 to form a loop to generate current . Therefore, a voltage difference is generated between the gate and the source of the fourth transistor Q4 through the first resistor R1, so that the drain and the source of the fourth transistor Q4 are turned on, so that the second voltage output terminal OUT2 The outputted second voltage can be output to the power output terminal V out through the fourth transistor Q 4 , thereby charging the electrical device 30 electrically connected to the power output terminal V out .
此外,由于该电源转换器11是根据该第二电压输出端OUT2输出的电压进行反馈控制的,也就是说,该第二电压输出端OUT2是该电源转换器11的主反馈回路,该电源转换器11的控制单元115是根据该主反馈回路的电压,也就是该第二电压输出端OUT2输出的第二电压判断是否要输出该控制信号。当该第二电压超过一阀值时,代表目前该电源转换器11的输出电压过高,因此该控制单元115便会暂停输出该控制信号,藉此使该电源转换器11的输出电压恢复到正常值,也就是该阀值以下,且该控制单元115于该第二电压未超过该阀值时,便会持续输出该控制信号,使该电源转换器11输出该第一电压与该第二电压。In addition, since the power converter 11 performs feedback control according to the voltage output by the second voltage output terminal OUT2, that is to say, the second voltage output terminal OUT2 is the main feedback loop of the power converter 11, the power conversion The control unit 115 of the controller 11 determines whether to output the control signal according to the voltage of the main feedback loop, that is, the second voltage output by the second voltage output terminal OUT2. When the second voltage exceeds a threshold, it means that the current output voltage of the power converter 11 is too high, so the control unit 115 suspends outputting the control signal, thereby restoring the output voltage of the power converter 11 to The normal value, that is, below the threshold value, and the control unit 115 will continue to output the control signal when the second voltage does not exceed the threshold value, so that the power converter 11 outputs the first voltage and the second voltage Voltage.
因此,当该电器设备被移除时,原本由该第一电压输出端OUT1通过该第一电阻R1及该第三分压电路125电连接至该接地端GND而形成回路所产生电流会因为该电器设备30被移除,而反流馈入该第二电压输出端OUT2,使该第二电压输出端OUT2输出的第二电压超过该阀值。此时,由于该第二电压输出端OUT2输出的第二电压超过该阀值,该控制单元115暂停输出该控制信号,而当该控制单元115未输出该控制信号时,该第一二次侧耦合线圈113与该第二二次侧耦合线圈114便不会耦合产生电压值。因此该第一电压输出端OUT1输出的第一电压便会开始下降,但是因为该第二电压输出端OUT2会接收到反流馈入的电流,使该第二电压输出端OUT2输出的第二电压会维持超过该阀值而不会下降。Therefore, when the electrical equipment is removed, the current originally generated by the first voltage output terminal OUT1 being electrically connected to the ground terminal GND through the first resistor R1 and the third voltage dividing circuit 125 to form a loop will be caused by The electrical equipment 30 is removed, and the feedback is fed into the second voltage output terminal OUT2, so that the second voltage output by the second voltage output terminal OUT2 exceeds the threshold value. At this time, since the second voltage output by the second voltage output terminal OUT2 exceeds the threshold value, the control unit 115 suspends outputting the control signal, and when the control unit 115 does not output the control signal, the first secondary side The coupling coil 113 and the second secondary side coupling coil 114 are not coupled to generate a voltage value. Therefore, the first voltage output by the first voltage output terminal OUT1 will start to decrease, but because the second voltage output terminal OUT2 will receive the current fed in by the reverse current, the second voltage output by the second voltage output terminal OUT2 will be reduced. will remain above this threshold without falling.
由于该第一电压输出端OUT1输出的第一电压开始下降,因此当该处理单元121判断该第一电压输出端OUT1的电压值小于该关闭临界值时,该处理单元产生该关闭信号自该第一输出端输出至该第一晶体管Q1的栅极,使该第一晶体管Q1进入截止状态,进而使该第四晶体管Q4进入截止状态,且让该电子断路器12回到待机状态。Since the first voltage output by the first voltage output terminal OUT1 begins to drop, when the processing unit 121 determines that the voltage value of the first voltage output terminal OUT1 is smaller than the shutdown threshold, the processing unit generates the shutdown signal from the first voltage output terminal OUT1. An output terminal is outputted to the gate of the first transistor Q1, so that the first transistor Q1 is turned off, and then the fourth transistor Q4 is turned off, and the electronic circuit breaker 12 is returned to the standby state.
综上所述,本发明通过电子断路器12的运作,当该电器设备作为负载电连接在该电源输出端Vout与该接地端GND之间时,该电子断路器12便可被启动,使该电源转换器11的第二电压输出端OUT2的第二电压能够被输出至该电源输出端Vout,藉此对该电器设备进行充电。当该电器设备充电完毕而被移开时,该电子断路器12便可被关闭,切断该电源转换器12的第二电压输出端OUT2与该电源输出端Vout的连接。如此一来,即便该电源输出端Vout被外露在外壳外面,当电器设备30没有在充电的时候,该电源输出端Vout不会输出该第二电压,因此使用者也不会因为误触而被电击,进而提高使用的安全性。To sum up, in the present invention, through the operation of the electronic circuit breaker 12, when the electrical device is electrically connected between the power output terminal V out and the ground terminal GND as a load, the electronic circuit breaker 12 can be activated, so that the electronic circuit breaker 12 can be activated. The second voltage of the second voltage output terminal OUT2 of the power converter 11 can be output to the power output terminal V out , thereby charging the electrical device. When the electrical equipment is charged and removed, the electronic circuit breaker 12 can be turned off to cut off the connection between the second voltage output terminal OUT2 of the power converter 12 and the power output terminal V out . In this way, even if the power output terminal V out is exposed outside the casing, when the electrical device 30 is not being charged, the power output terminal V out will not output the second voltage, so the user will not touch it by mistake. And the electric shock, thereby improving the safety of use.

The fifth transistor Q5 The source of 5 is electrically connected to the ground terminal GND. The sixth transistor Q6 has a drain, a gate and a source, the drain of the sixth transistor Q6 is electrically connected to the base of the third transistor Q3 , and the gate of the sixth transistor Q6 The drain electrode of the fifth transistor Q5 is electrically connected, and the source electrode of the sixth transistor Q6 is electrically connected to the ground terminal GND. The second voltage output terminal OUT2 is electrically connected to the drain of the fifth transistor Q5 through the second resistor R2. The first capacitor C1 is electrically connected between the base of the third transistor Q3 and the ground terminal GND.
由于该第五晶体管Q5的栅极与源极与该第一晶体管Q1的栅极与源极的连接方式相同,因此当第一晶体管Q1进入导通状态时,该第五晶体管Q5也同样地会一起进入导通状态。而当该第五晶体管Q5进入导通状态时,该第六晶体管Q6的基极连接至该接地端GND,使该第六晶体管Q6进入截止状态。此外,如上述说明,当该第一晶体管Q1进入导通状态时,该第二晶体管Q2也会进入导通状态,因此该第一电压输出端OUT1便可通过该第二晶体管Q2对该第一电容C1充电,并让该第三晶体管Q3的基极的电压能随着该第一电容C1的充电而慢慢被提高,藉此软性启动(soft start)该电子断路器12。而该第一电容C1的电容值能够决定该第三晶体管Q3的基极的电压的提升速度,因此用者能通过设计该第一电容C1的电容值,设定该电子断路器12的软性启动时间。Since the gate and source of the fifth transistor Q5 are connected in the same manner as the gate and source of the first transistor Q1, when the first transistor Q1 enters the conducting state, the fifth transistor Q5 In the same way, they will be turned on together. When the fifth transistor Q5 enters an on state, the base of the sixth transistor Q6 is connected to the ground terminal GND, so that the sixth transistor Q6 enters an off state. In addition, as described above, when the first transistor Q1 enters the conducting state, the second transistor Q2 also enters the conducting state, so that the first voltage output terminal OUT1 can pass through the second transistor Q2 to pair The first capacitor C1 is charged, and the voltage of the base of the third transistor Q3 can be gradually increased along with the charging of the first capacitor C1 , thereby soft-starting the electronic circuit breaker device 12. The capacitance value of the first capacitor C 1 can determine the speed of increasing the voltage of the base of the third transistor Q 3 , so the user can set the electronic circuit breaker 12 by designing the capacitance value of the first capacitor C 1 . soft-start time.
进一步而言,请参阅图5所示,该具有电子断路器的电源供应设备的一第四较佳实施例与上述的第三较佳实施例相同,但该电子断路器12进一步包含有一反馈电流产生电路127,该反馈电流产生电路127包含有一第七晶体管Q7、一第八晶体管Q8、一第三电阻R3、一第四电阻R4及一第五电阻R5。Further, please refer to FIG. 5 , a fourth preferred embodiment of the power supply device with an electronic circuit breaker is the same as the above-mentioned third preferred embodiment, but the electronic circuit breaker 12 further includes a feedback current The generating circuit 127 includes a seventh transistor Q 7 , an eighth transistor Q 8 , a third resistor R 3 , a fourth resistor R 4 and a fifth resistor R 5 .
该第七晶体管Q7具有一漏极、一栅极及一源极,该第七晶体管Q7的栅极电连接至该处理单元121的一第二输出端O/P2,该第七晶体管Q7的源极电连接至该接地端GND。该第八晶体管Q8具有一射极、一基极及一集极,该射极电连接至该第一电压输出端OUT1。The seventh transistor Q7 has a drain, a gate and a source. The gate of the seventh transistor Q7 is electrically connected to a second output terminal O/P2 of the processing unit 121. The seventh transistor Q7 The source of 7 is electrically connected to the ground terminal GND. The eighth transistor Q8 has an emitter, a base and a collector, and the emitter is electrically connected to the first voltage output terminal OUT1.
该第八晶体管Q8的射极通过该第三电阻R3电连接至该第八晶体管Q8的基极。该第八晶体管Q8的基极通过该第四电阻R4电连接至该第七晶体管Q7的漏极。该第八晶体管Q8的集极通过该第五电阻R5电连接至该电压输出端Vout。在本较佳实施例中,更详细地来说,该第八晶体管Q8的集极是通过该第五电阻R5电连接至该第四晶体管Q4的漏极。The emitter of the eighth transistor Q8 is electrically connected to the base of the eighth transistor Q8 through the third resistor R3 . The base of the eighth transistor Q8 is electrically connected to the drain of the seventh transistor Q7 through the fourth resistor R4. The collector of the eighth transistor Q8 is electrically connected to the voltage output terminal Vout through the fifth resistor R5. In this preferred embodiment, in more detail, the collector of the eighth transistor Q8 is electrically connected to the drain of the fourth transistor Q4 through the fifth resistor R5.
且当该处理单元121判断该电源输出端Vout的电压值小于该启动临界值时,该处理单元121进一步产生一反馈电流启动信号自该第二输出端O/P2输出,控制该第七晶体管Q7及该第八晶体管Q8导通。And when the processing unit 121 determines that the voltage value of the power output terminal V out is less than the activation threshold, the processing unit 121 further generates a feedback current activation signal output from the second output terminal O/P2 to control the seventh transistor. Q7 and the eighth transistor Q8 are turned on.
而当该处理单元121判断该第一电压输出端OUT1的电压值小于该关闭临界值时,该处理单元121进一步产生一反馈电流关闭信号自该第二输出端O/P2输出,控制该第七晶体管Q7及该第八晶体管Q8断开。When the processing unit 121 determines that the voltage value of the first voltage output terminal OUT1 is less than the shutdown threshold, the processing unit 121 further generates a feedback current shutdown signal output from the second output terminal O/P2 to control the seventh output terminal OUT1 The transistor Q7 and the eighth transistor Q8 are turned off.
举例来说,当该电器设备电连接至该电源输出端Vout进行充电时,该处理单元121除了产生该启动信号使该第四晶体管Q4导通外,该处理单元121还进一步产生该反馈电流启动信号自该第二输出端O/P2输出至该第七晶体管Q7的栅极。该第七晶体管Q7因为接收到该反馈电流启动信号而被导通,进而使该第八晶体管Q8导通,且该第一电压输出端OUT1能通过导通的该第八晶体管Q8及该第五电阻R5连接至该第四晶体管Q4的漏极,并产生一反馈电流通过该第四晶体管Q4对该电器设备充电。For example, when the electrical device is electrically connected to the power output terminal V out for charging, the processing unit 121 generates the feedback signal in addition to generating the enable signal to turn on the fourth transistor Q 4 , the processing unit 121 further generates the feedback A current enable signal is output from the second output terminal O/P2 to the gate of the seventh transistor Q7. The seventh transistor Q7 is turned on because it receives the feedback current enable signal, so that the eighth transistor Q8 is turned on, and the first voltage output terminal OUT1 can pass through the turned-on eighth transistor Q8 and The fifth resistor R5 is connected to the drain of the fourth transistor Q4 , and generates a feedback current to charge the electrical device through the fourth transistor Q4 .
然而,当该电器设备被移除时,该反馈电流无法继续输出至该电源输出端Vout,因此,该反馈电流便会反流馈入该第二电压输出端OUT2。如上所述,反流馈入该第二电压输出端OUT2的反馈电流使该第二电压输出端OUT2输出的第二电压超过该阀值,进而使该电源转换器11的该控制单元115暂停输出该控制信号,让该第一电压输出端OUT1的电压值开始下降而低于该关闭临界值。However, when the electrical device is removed, the feedback current cannot continue to be output to the power output terminal V out , so the feedback current is fed back into the second voltage output terminal OUT2 . As described above, the feedback current fed into the second voltage output terminal OUT2 causes the second voltage output from the second voltage output terminal OUT2 to exceed the threshold value, thereby causing the control unit 115 of the power converter 11 to suspend the output The control signal causes the voltage value of the first voltage output terminal OUT1 to start to drop below the shutdown threshold.
此外,当该电器设备被移除时,该处理单元121除了产生该关闭信号使该第四晶体管Q4进入截止状态外,该处理单元121还进一步产生该反馈电流关闭信号自该第二输出端O/P2输出至该第七晶体管Q7的栅极。该第七晶体管Q7因为接收到该反馈电流关闭信号而被截止,使该第八晶体管Q8断开,进而停止产生该反馈电流。In addition, when the electrical device is removed, in addition to generating the turn-off signal to make the fourth transistor Q4 turn off, the processing unit 121 further generates the feedback current turn-off signal from the second output terminal O/P2 is output to the gate of the seventh transistor Q7. The seventh transistor Q7 is turned off because it receives the feedback current shutdown signal, so that the eighth transistor Q8 is turned off, thereby stopping generating the feedback current.
通过进一步设置该反馈电流产生电路127能使得在电器设备被移除时,反馈流回该第二电压输出端OUT2的电流增加,缩短该电源转换器11的该控制单元115暂停输出该控制信号的判断时间,藉此提高工作效率。By further disposing the feedback current generating circuit 127, when the electrical device is removed, the feedback current flowing back to the second voltage output terminal OUT2 increases, shortening the period of time during which the control unit 115 of the power converter 11 suspends outputting the control signal. Judge the time to improve work efficiency.
再请参阅图6所示,该具有电子断路器的电源供应设备的一第五较佳实施例与上述的第四较佳实施例大致相同,其中不同之处在于,该电子断路器12的反馈电流产生电路127的该第八晶体管Q8是通过该第五电阻R5电连接至该第四晶体管Q4的源极。Referring again to FIG. 6 , a fifth preferred embodiment of the power supply device with electronic circuit breaker is substantially the same as the above-mentioned fourth preferred embodiment, and the difference is that the feedback of the electronic circuit breaker 12 The eighth transistor Q8 of the current generating circuit 127 is electrically connected to the source of the fourth transistor Q4 through the fifth resistor R5.
进一步而言,在上述该具有电子断路器的电源供应设备的第一至第五较佳实施例中,该处理单元121在产生该启动信号自该第一输出端O/P1输出后,该处理单元121进一步判断该电源输出端Vout的电压值是否小于一短路临界值。Further, in the above-mentioned first to fifth preferred embodiments of the power supply device with electronic circuit breaker, after the processing unit 121 generates the activation signal and outputs it from the first output terminal O/P1, the processing The unit 121 further determines whether the voltage value of the power output terminal V out is less than a short-circuit threshold.
当该处理单元121判断该电源输出端Vout的电压值小于该短路临界值时,该处理单元121产生该关闭信号自该第一输出端O/P1输出,控制该电子开关122断开,且该处理单元121进一步判断该电源输出端Vout的电压值是否大于一待机临界值;当该处理单元121判断该电源输出端Vout的电压值大于该待机临界值时,该处理单元121重新执行该待机模式。When the processing unit 121 determines that the voltage value of the power output terminal V out is less than the short-circuit threshold value, the processing unit 121 generates the shutdown signal from the first output terminal O/P1 to output, controls the electronic switch 122 to turn off, and The processing unit 121 further determines whether the voltage value of the power output terminal V out is greater than a standby threshold value; when the processing unit 121 determines that the voltage value of the power output terminal V out is greater than the standby threshold value, the processing unit 121 re-executes the standby mode.
当该处理单元121判断该电源输出端Vout的电压值不小于该短路临界值时,该处理单元121才开始判断该第一电压输出端OUT1的电压值是否小于该关闭临界值,后续作动原理如上所述,在此不再赘述。When the processing unit 121 determines that the voltage value of the power output terminal V out is not less than the short-circuit threshold value, the processing unit 121 starts to determine whether the voltage value of the first voltage output terminal OUT1 is less than the shutdown threshold value, and subsequent operations The principle is as described above and will not be repeated here.
当使用者不小心误触外露的该电源输出端Vout,导致该电源输出端Vout与该接地端GND短路时,该电源输出端Vout的电压值会与该接地端GND相同,皆为0伏特。然而,当该电源输出端Vout与该接地端GND短路时,该处理单元121将会判断该电源输出端Vout的电压值小于该启动临界值,进而产生该启动信号控制该电子开关导通。但此时并非是该电器设备连接上该电源输出端Vout需要进行充电的状况,此状况是使用者误触而导致的错误的启动状态。When the user accidentally touches the exposed power output terminal V out , resulting in a short circuit between the power output terminal V out and the ground terminal GND, the voltage value of the power output terminal V out will be the same as the ground terminal GND, both of which are 0 volts. However, when the power output terminal V out and the ground terminal GND are short-circuited, the processing unit 121 will determine that the voltage value of the power output terminal V out is less than the activation threshold, and then generate the activation signal to control the electronic switch to turn on . However, at this time, it is not a situation that the electrical equipment needs to be charged when connected to the power output terminal V out , but this situation is an erroneous start-up state caused by the user's accidental touch.
因此,为了避免这种错误的启动状况,当该处理单元121判断该电源输出端Vout的电压值小于该启动临界值而产生该启动信号后,该处理单元121进一步判断该电源输出端Vout的电压值是否还小于该短路临界值。且当该处理单元121判断该电源输出端Vout小于该短路临界值时,代表目前为错误的启动的状态,因此该处理单元121便会产生该关闭信号使该电子开关122关闭。而当该处理单元121判断该电源输出端Vout小于该启动临界值且大于该短路临界值时,才代表目前状态为正常的启动状态。Therefore, in order to avoid such an erroneous start-up situation, when the processing unit 121 determines that the voltage value of the power output terminal V out is less than the start-up threshold to generate the start-up signal, the processing unit 121 further determines the power output terminal V out Whether the voltage value is still less than the short-circuit critical value. And when the processing unit 121 determines that the power output terminal V out is smaller than the short-circuit threshold, it means that the current state is wrongly activated, so the processing unit 121 generates the shutdown signal to turn off the electronic switch 122 . When the processing unit 121 determines that the power output terminal V out is smaller than the startup threshold and greater than the short-circuit threshold, it indicates that the current state is a normal startup state.
此外,当该处理单元121判断该电源输出端Vout小于该短路临界值,且产生该关闭信号使该电子开关122关闭后,该处理单元121还需进一步判断短路的状态是否已经解除。因此,当该处理单元121判断该电源输出端Vout小于该短路临界值,且产生该关闭信号使该电子开关122关闭后,该处理单元121还需进一步判断该电源输出端Vout的电压值是否大于该待机临界值。当该电源输出端Vout的电压值大于该待机临界值时,代表短路状态已经解除,该处理单元121便可重新执行该待机模式。在本较佳实施例中,该待机临界值大于该短路临界值。In addition, when the processing unit 121 determines that the power output terminal V out is less than the short-circuit threshold and generates the shutdown signal to turn off the electronic switch 122 , the processing unit 121 needs to further determine whether the short-circuit state has been released. Therefore, when the processing unit 121 determines that the power output terminal V out is less than the short-circuit threshold and generates the shutdown signal to turn off the electronic switch 122 , the processing unit 121 needs to further determine the voltage value of the power output terminal V out Is it greater than the standby threshold. When the voltage value of the power output terminal V out is greater than the standby threshold, it means that the short-circuit state has been released, and the processing unit 121 can execute the standby mode again. In this preferred embodiment, the standby threshold is greater than the short-circuit threshold.

The base of the tenth transistor Q10 is electrically connected to the drain of the eleventh transistor Q11 through the second seventh resistor R27 and the second diode D2.
该第二电压输出端OUT2通过该第二电容C2电连接至该接地端GND。The second voltage output terminal OUT2 is electrically connected to the ground terminal GND through the second capacitor C 2 .
当该电器设备未电连接至该电源输出端Vout进行充电时,该电源输出端Vout的电压值维持在大于该启动临界值的状态。因此该电源输出端Vout输出的电压可通过该第二二电阻R22传送至该开关单元U1的控制端,使该开关单元U1维持在导通状态,进而使该第十一晶体管Q11的栅极接地,让该第十一晶体管Q11维持在截止状态。进一步而言,当该第十一晶体管Q11维持在截止状态时,该第九晶体管Q9及该第十晶体管Q10的基极无法接地,因而使该第九晶体管Q9及该第十晶体管Q10也维持在截止状态。When the electrical device is not electrically connected to the power output terminal V out for charging, the voltage value of the power output terminal V out is maintained at a state greater than the startup threshold. Therefore, the voltage output by the power output terminal V out can be transmitted to the control terminal of the switch unit U 1 through the second two resistors R 22 , so that the switch unit U 1 is maintained in an on state, thereby enabling the eleventh transistor Q The gate of 11 is grounded to keep the eleventh transistor Q11 in an off state. Further, when the eleventh transistor Q11 is maintained in an off state, the bases of the ninth transistor Q9 and the tenth transistor Q10 cannot be grounded, so that the ninth transistor Q9 and the tenth transistor Q10 cannot be grounded. Q 10 also remains off.
此时,由于该第九晶体管Q9及该第十晶体管Q10都在截止状态,该第一电压输出端OUT1及该第二电压输出端OUT2便无法通过该第九晶体管Q9及该第十晶体管Q10连接至该电子断路器12,使该电子断路器12无法接收到该电源转换器11输出的电力,藉此减少该电子断路器12的待机电力消耗。At this time, since the ninth transistor Q9 and the tenth transistor Q10 are both in the off state, the first voltage output terminal OUT1 and the second voltage output terminal OUT2 cannot pass through the ninth transistor Q9 and the tenth transistor Q10. The transistor Q 10 is connected to the electronic circuit breaker 12 so that the electronic circuit breaker 12 cannot receive the power output by the power converter 11 , thereby reducing the standby power consumption of the electronic circuit breaker 12 .
然而,当该电器设备一开始电连接至该电源输出端Vout时,该电源输出端Vout的电压值会降低,进而使该开关单元U1的控制端的电压值降低,让该开关单元U1变为截止状态。当该开关单元U1变为截止状态时,该第二电压输出端OUT2便可通过该第二三电阻R23、该第四二极管D4及该第二八电阻R28形成回路,产生电流,使该第十一晶体管Q11导通。当该第十一晶体管Q11导通时,该第九晶体管Q9及该第十晶体管Q10也会导通。However, when the electrical device is initially electrically connected to the power output terminal V out , the voltage value of the power output terminal V out will decrease, thereby reducing the voltage value of the control terminal of the switch unit U 1 . 1 becomes the off state. When the switch unit U1 is turned off, the second voltage output terminal OUT2 can form a loop through the second third resistor R 23 , the fourth diode D 4 and the second eight resistor R 28 to generate current, so that the eleventh transistor Q11 is turned on. When the eleventh transistor Q11 is turned on, the ninth transistor Q9 and the tenth transistor Q10 are also turned on.
此时,由于该第九晶体管Q9及该第十晶体管Q10都在导通状态,该第一电压输出端OUT1及该第二电压输出端OUT2便能够连接至该电子断路器12,使该电子断路器12接收到该电源转换器11输出的电力,而正常运作。At this time, since the ninth transistor Q9 and the tenth transistor Q10 are both in the conducting state, the first voltage output terminal OUT1 and the second voltage output terminal OUT2 can be connected to the electronic circuit breaker 12, so that the The electronic circuit breaker 12 receives the power output by the power converter 11 and operates normally.
此外,当该电器设备电连接至该电源输出端Vout进行充电时,该电源输出端Vout的电压值会与该第二电压输出端OUT2的电压值相同,也就是说,该开关单元U1会导通。但是当该电器设备电连接至该电源输出端Vout进行充电时,该电子断路器12的处理单元121的第一输出端O/P会输出该启动信号,且该处理单元121的第一输出端O/P通过该第三二极管D3电连接至该第十一晶体管Q11的栅极。因此,该第十一晶体管Q11便可通过该处理单元121的第一输出端O/P输出的启动信号维持在导通状态,使该电源转换器11输出的电力能持续通过导通的该第九晶体管Q9及该第十晶体管Q10而输出至该电子断路器12而维持正常运作。In addition, when the electrical device is electrically connected to the power output terminal V out for charging, the voltage value of the power output terminal V out will be the same as the voltage value of the second voltage output terminal OUT2 , that is, the switch unit U 1 will turn on. However, when the electrical device is electrically connected to the power output terminal V out for charging, the first output terminal O/P of the processing unit 121 of the electronic circuit breaker 12 will output the activation signal, and the first output terminal O/P of the processing unit 121 will output the activation signal. The terminal O/P is electrically connected to the gate of the eleventh transistor Q11 through the third diode D3 . Therefore, the eleventh transistor Q11 can be maintained in a conducting state through the start-up signal output by the first output terminal O/P of the processing unit 121, so that the power output by the power converter 11 can continue to pass through the conducting signal. The ninth transistor Q9 and the tenth transistor Q10 are output to the electronic circuit breaker 12 to maintain normal operation.
