采样控制理论中有一个重要结论:冲量相等而形状不同的窄脉冲加在具有惯性的环节上时,其效果基本相同.PWM控制技术就是以该结论为理论基础,对半导体开关器件的导通和关断进行控制,使输出端得到一系列幅值相等而宽度不相等的脉冲,用这些脉冲来代替正弦波或其他所需要的波形.按一定的规则对各脉冲的宽度进行调制,既可改变逆变电路输出电压的大小,也可改变输出频率.-Sampling control theory has an important conclusion: the impulse is equal bu

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-
