摘要
空间矢量脉宽调制(Space Vector Pulse Width Modulation, SVPWM)是当电源为三相对称正弦电压时,以三相电动机定子的磁链轨迹圆为参考,让三相逆变器做适当的开关动作,从而形成PWM波,以所形成的实际磁链矢量来跟踪精确的磁链轨迹圆。SVPWM方法将逆变系统和异步电动机当作一个整体来考虑,具有模型简单,便于微处理器实时控制等优点。文章以SVPWM原理为基础,通过Simulink进行仿真实现。
Space vector pulse width modulation（SVPWM）is when the power supply is three-phase symmetrical sinusoidal voltage, the flux track circle of the stator of the three-phase motor is taken as a reference, and the three-phase inverter is allowed to make appropriate switching action, thus forming PWM waves, and tracking the precise flux track circle with the actual flux vector formed. SVPWM considers the inverter system and asynchronous motor as a whole. The model is simple and convenient for real-time control of microprocessor. This paper is based on the SVPWM principle and is simulated by Simulink.
