摘要
为了消除矢量控制中的偶次谐波,在分析了偶次谐波产生的原因的基础上,提出了一种能够消除偶次谐波并减少开关损耗的SVPWM算法。该算法将常规的7段式开关顺序变为了5段式开关顺序,减少了开关次数,从而既降低了开关损耗,又消除了偶次谐波。文章最后利用Matlab/Simulink对该算法进行了仿真,验证了该算法的正确性与可行性。
In order to eliminate the even harmonic vector control,the reasons causing even order harmonics are analyzed,and a novel SVPWM algorithm,which can eliminate the even harmonics and reduce the switching losses,is put forward.In the algorithm,the seven-stages-switch order is replaced by the five-stages-switch order to reduce the number of order switch.As a result,the switch loss is reduced,and even order harmonics is eliminated as well.The simulation testing is carried out by using Matlab/Simulink.The experimental results show that the algorithm is valid and feasible.
