摘　　要：本文推出一种高正弦度半软开关交流调压调速节电装置，引入了非谐振式半软开关的概念及其实现方式，给出了PSPICE仿真和实验结果，并与现有的典型VVVF变频节电调速方案作了经济技术指标的综合比较。A variable voltage speed control with half soft switching and low sinusoidal distortion is introduced in this paper. A half soft switching mode not by present reasonant theory is proposed,as well as the realization. Simulation by PSPICE to this system and the experimental results are presented,and a synthetic comparisons between VVVF Inverter speed control and the novel VV speed control are also given out in this paper.
