摘　　要：本文详细讨论了开关点预置SPWM控制方案的理论,采用13块波的开关点预置最优SPWM控制方案。采取此种控制方案在满足输出性能指标(如提高了输出电压质量)的前提下,还具有开关频率低、系统损耗小、系统效率高以及直流利用率高等优点。This paper discusses the theory of switching-node preset optimal SPWM in detail. Further taking the inverter used for main power module as an example,the paper studies a new control strategy of 13-wave-modulation. By the algorithm, the output voltage is promoted,and it makes the inverter has lower switching frequency and smaller loss,and efficiency of the system increased.
