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。
Compared with bipolar modulating, advantages and disadvantages of mono pole modulating of SPWM inverter power supply are analyzed, and a novel method is proposed that the dead time is set during the phase converting of sinusoidal fundamental wave. Explication of its theory is given and the result of the relative PSPICE simulation is presented.
