摘　　要：为了解决传统空间矢量脉宽调制(SVPWM)实现比较复杂的问题,针对异步电动机变压变频(VVVF)控制,设计了一种SVPWM实现方案,详细推导了所设计SVPWM算法的扇区判断和矢量作用时间。最后,利用该算法制作了VVVF变频器样机,驱动三相异步电动机的实验结果验证了该算法的可行性。To solve complex issues of the traditional space vector pulse width modulation （SVPWM） , a novel SVPWM method was design for induction motor controlled by variable voltage and variable frequency （VVVF）. The judgment of voltage vector space＇s sector and the action time of basis synthetic vector were obtained. The VVVF inverter was built by using the novel SVPWM for three-phase asynchronous motors. The experimental results verify the feasibility of the algorithm.
