Description
本新型是關於控制單元及電源供應器，且特別是有關於應用於導通或截止P通道半導體開關的控制單元及具有前述控制單元的電源供應器。The present invention relates to a control unit and a power supply, and more particularly to a control unit for turning on or off a P-channel semiconductor switch and a power supply having the aforementioned control unit.
電源轉換模組主要用以提供電子裝置操作電力。為了避免在電源轉換模組輸出的電力的電壓超過電子裝置額定電壓(過電壓)造成電子裝置的毀損，一般會在電源轉換模組的輸出端裝設P通道半導體開關以提供過電壓保護效果。The power conversion module is mainly used to provide operating power of the electronic device. In order to prevent the voltage of the power outputted by the power conversion module from exceeding the rated voltage (overvoltage) of the electronic device, the P-channel semiconductor switch is generally installed at the output end of the power conversion module to provide an over-voltage protection effect.
在電源轉換模組輸出的電力的電壓不超過電子裝置的額定電壓時，P通道半導體開關導通，則電源轉換模組輸出的電力可以傳遞至電子裝置；而當電源轉換模組輸出的電力的電壓超過電子裝置的額定電壓時，P通道半導體開關截止，電源轉換模組輸出的電力無法傳遞至電子裝置，以達過電壓保護效果。When the voltage of the power outputted by the power conversion module does not exceed the rated voltage of the electronic device, the P-channel semiconductor switch is turned on, and the power output from the power conversion module can be transmitted to the electronic device; and when the voltage of the power output from the power conversion module is When the rated voltage of the electronic device is exceeded, the P-channel semiconductor switch is turned off, and the power output from the power conversion module cannot be transmitted to the electronic device to achieve the voltage protection effect.
在P通道半導體開關導通時，其電流輸入端(即源極)及控制端(即閘極)間會蓄積電荷，此蓄積電荷使得P通道半導體開關的反應時間增加，無法即時的提供過電壓保護(即發生過電壓保護延遲的問題)，造成電子裝置損壞的機率提高。When the P-channel semiconductor switch is turned on, a charge is accumulated between the current input terminal (ie, the source) and the control terminal (ie, the gate). This accumulated charge increases the reaction time of the P-channel semiconductor switch, and cannot provide over-voltage protection instantaneously. (ie, the problem of overvoltage protection delay occurs), the probability of damage to the electronic device is increased.

The power supply includes a switch control unit 10, a power conversion module 20, and an electronic device RL. The power conversion module 20 is configured to output a DC power source, which may be, for example, a power converter that converts AC power into a DC power source and outputs a DC power source.

在圖1的開關控制單元中，當第一切換件Q1受到控制器110控制而導通時，會讓P通道半導體開關SW同步閉合而導通，則電源轉換模組20的輸出端Out輸出的電力可以傳遞至電子裝置RL。當第一切換件Q1受到控制器110控制而截止時，在P通道半導體開關SW的電流輸入端S及控制端G間積蓄的電荷形成的電壓差可以讓第二切換件Q2導通，藉此，積蓄在P通道半導體開關SW的電流輸入端S及控制端G間的電荷便能夠通過導通的第二切換件Q2進行放電。如此一來，當第一切換件Q1再次受到控制器110的控制而導通時，P通道半導體開關SW即可快速反應，以達保護電子裝置RL的效果。再者，本新型的開關控制單元同時具備電路複雜度低以及體積小等特點。In the switch control unit of FIG. 1, when the first switching device Q1 is controlled by the controller 110 to be turned on, the P-channel semiconductor switch SW is synchronously closed and turned on, and the output power of the output terminal Out of the power conversion module 20 can be Transfer to the electronic device RL. When the first switching element Q1 is controlled by the controller 110 to be turned off, the voltage difference formed by the charge accumulated between the current input terminal S and the control terminal G of the P-channel semiconductor switch SW can turn on the second switching element Q2, whereby The electric charge accumulated between the current input terminal S and the control terminal G of the P-channel semiconductor switch SW can be discharged by the turned-on second switching member Q2. In this way, when the first switching device Q1 is turned on again by the control of the controller 110, the P-channel semiconductor switch SW can quickly react to protect the effect of the electronic device RL. Furthermore, the switch control unit of the present invention has the characteristics of low circuit complexity and small size.
