摘　　要：本文对基于EPWM的双向逆变器的原理和控制方法进行了研究。应用电力电子技术设计了一个单相正弦波输出双向逆变稳压电源,实现电网侧负载侧能量的双向传输。逆变电路采用单相IGBT双H桥式逆变电路,负载侧逆变器采用双极性EPWM调制方案,实现不需要频繁切换功率开关情形下电压平滑连续可调。This paper illustrated the study of the principles and control techniques of double-sided electrical converters based on dual polar EPWM techniques. Power electronic technologies are applied in＇ the design of a single-phase double-sided converter. It can make power energy double-sided flew and also completed stabilizing voltage without changing IGBT switch frequently.
