摘　　要：用时域分析的方法将电网的畸变电流分解成与电压波形一致的有功分量和不一致的无功分量.给出了一种采用脉宽调制(PWM)的补偿电流源,补偿其无功分量,消除和抑制,电网波形的畸变.In this paper the deformed electric current of power network is separated into the work amount with the voltage wave and the non-work amount not keeping with the voltage wave by analyzing the time function. A new method of eliminating and controlling the deformation of power network wave is presented by use of pulse wide modulated electric current source compensated for the non-work amount.
