摘　　要：介绍了适用于脉冲功率技术大容量电容器组快速高效充电的一种变频恒流高压电源 ,它采用三相半控晶闸管桥式整流 ,经由两只开关管、储能电感、续流二极管和霍尔电流传感器构成的恒流网络 ,再由桥式晶闸管电路逆变成 1 k Hz后升压、整流。A constant current high voltage power supply is described, which is used to charging the capacitor banks quickly and efficiently in pulse power technology. The three phase alternating current is rectified with the half-controlled bridge mode of Silicon Controlled Rectifier(SCR), then, is imported into the constant current network consisted of two SCR, storage energy inductance, continuous current diode and Hall sensor, thirdly is changed inversely into 1kHz A.C by the self controlled SCR bridge circuit, finally, is put into a step up transformer and rectified by SCR.

关 键 词：变频恒流高压电源 电流传感器 晶闸管
