摘要
分析了 SPWM逆变电源的单极调制技术相对于双极调制技术的优缺点 ,提出了一种只在正弦基波换相处设置死区时间的新方法 .阐述其机理并把它和传统的 RC延时电路设置死区的方法作了比较 .最后给出其
Advantages and disadvantages of monopole modulati ng of inverter power supply correspond to bipolar modulating are analyzed,and a new method is proposed that the dead-time is set during the phase converting of sinusoidal fundamental wave. Explication of its theory is given a nd at the same time this method is compared with the traditional dead-time setting method by RC delay circuit. A t last, the result of the relative PSPICE simulation is presented.
