| 摘 要： | 介绍了一种应用于高压侧电子装置中的电源方案:通过一个特制的电流互感器(CT),直接从高压侧一次母线电流获取电能,凭借在CT和整流桥之间串联的一个电感,大大降低了施加在整流桥上的感应电压并限制了CT的输出电流,起到了稳定电压和保护后续电路的作用,成功地解决了高压侧有源电子设备的电源问题。

| Abstract: | This paper introduces a design of power supply source applied in high voltage electronic system.The energy is obtained directly from the power line by some tailor-made current transformer(CT).By setting an inductance in series with the CT and the rectifier bridge,the voltage on the rectifier is reduced to the acceptable level and the output current from the CT is also limited to very small.Thus,the inductance helps steady the voltage and protects the follow circuit.It can resolve the problem of power supply in high voltage electronic instrument. |
