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，也便于微处理器的实时控制。(The main idea of SVPWM is that the ideal magnetic chain circle of the three-phase symmetrical motor is used as the reference standard when the three-phase symmetric sine wave voltage is supplied, and the PWM wave is formed by the proper switching of the three phase inverters in different switching modes, and the accurate magnetic chain circle is traced with the actual flux vector formed. The traditional SPWM method starts from the angle of the power supply to generate a frequency modulation voltage regulating sinusoidal power supply. While the SVPWM method considers the inverter system and asynchronous motor as a whole, the model is simple and convenient for the real-time control of the microprocessor.)
