电压源SPWM逆变器的仿真研究

A Simulation Study for Voltage Source SPWM Inverter

采用通用的电子线路软件包ＰＳＰＩＣＥ对三相电压源ＳＰＷＭ 逆变器进行了仿真研究，采用开关函数法表示逆变器电流信号和电压信号。从而建立逆变器的宏模型，解决了程序在计算机上运行时间长和不收敛问题。仿真结果和实验是一致的。

This paper uses an electronic circuit software PSPICE to study three phase voltage source SPWM inverter by simulation.In order to solve unconverge and a long time operation of program in computer,a macromode of SPWM inverter is presented by switching functions formulating the signal of voltage and current of SPWM inverter.The result of simulation coincides with experiment.This paper presents a new way of simulation for power electronic
