SVPWM的主要思想是以三相对称正弦波电压供电时三相对称电动机定子理想磁链圆为参考标准，以三相逆变器不同开关模式作适当的切换，从而形成PWM波，以所形成的实际磁链矢量来追踪其准确磁链圆。传统的SPWM方法从电源的角度出发，以生成一个可调频调压的正弦波电源，而SVPWM方法将逆变系统和异步电机看作一个整体来考虑，模型比较简单-
The main idea is based on SVPWM symmetrical three-phase sine wave voltage supply three phase motor stator flux perfect circle as the reference standard, a different three-phase inverter for proper switch mode switching, thereby forming a PWM wave to the formation of actual flux vector to track its exact flux circle. The traditional method of SPWM from the power point of view, to generate a sine wave frequency modulation regulator power supply and the inverter system SVPWM method and asynchronous motors as a whole to consider, the model is relatively simple
