摘要
分析了空间电压矢量(SVPWM)的基本原理,给出了SVPWM技术的几种优化措施,并在此基础上提出一种根据负载功率因数角动态分配零矢量的方法。理论分析和仿真结果表明,采用该方法能达到最小开关损耗。
The principles of the Space vector PWM is introduced,and some concrete optimized methods of SVPWM are given. Then,a method is proposed to allocate the zero space vectors dynamically according to the power factor angle of the load .Theoretical analysis and simulation results show the minimum switch losses can be reached with this method.
