power switching

基本解释

When we use low-dropout switching power switching converter to reduce positive input voltage, we usually need an extra low- power negative output voltage.
在采用降压开关功率开关转换器降低正输入电压的同时，通常还需要一个额外的低功率负输出电压。
The main circuit is a half bridge series inverter and MOSFET is used for its power switching devices. PWM chip TL494 is the nucleus of the control circuit.
主电路采用半桥式结构，场效应管作为功率开关元件，集成芯片TL 494作为其控制电路的核心。
