Splet18. feb. 2024 · 所以SPWM就是在PWM的基础上用正弦波来调制合成的具有正弦波规律变化的方波。不过SPWM调试方式在FOC实现中并不常用，原因是SPWM要比后面要说的SVPWM的母线电压利用率要低15%。另一方面，从控制的角度来看，我们甚至根本就不想跟什么三个正弦波打交道！因为要对于非线性的信号进行准确控制就要使用复杂的高阶控 … Splet29. okt. 2024 · SVPWM比SPWM的电压利用率高15%，这是两者最大的区别，但两者并不是孤立的调制方式，典型的SVPWM是一种在SPWM的相调制波中加入了零序分量后进行规则采样得到的结果，因此SVPWM有对应SPWM的形式。. 反之，一些性能优越的SPWM方式也可以找到对应的SVPWM算法，所以 ...
