  1. This paper discussed the theory of switching - node preset optimal spwm detailedly, and got the solution of 9 waves, 13 waves, and 17 waves switching - node preset optimum spwm control strategy. furthermore, by means of raising the switching frequency, the quality of output voltage can be promoted, the resonate frequency of output filter can also be raised, which made the inverter smaller volume and lighter weight and more efficient

    本文首先對開關點預置最優spwm控制策略進行了深入研究,分別求解出了九塊波、十三塊波、十七塊波等情況下的最優spwm控制的開關角,並討論了在提高開關頻率之後進一步優化輸出濾波器設計,在保障系統效率的前提下,提高輸出波形質量和減小濾波器的體積重量。
