1、1、SVPWM 的定义交流电动机需要输入三相正弦电流的最终目的是在电动机空间形成圆形旋转磁场，从而产生恒定的 电磁转矩。把逆变器和交流电动机视为一体，以圆形旋转磁场为目的来控制逆变器的工作，这种控制方法称为“磁链跟踪控制”，磁链轨迹的控制是通过交替使用不同的电压空间矢量 来实现的，所以又称为“电压空间矢量PWM（space vector PWM,SVPWM）控制”矢量：既有大小又有方向的量。一般来说，在物理学中称作矢量，在数学中称作向量。2、空间矢量的定义：交流电动机绕组的电压、电流、磁链等物理量都是随时间变化的，如果考虑到他们所在绕组的空间位置，可以定义为空间矢量。A、B、C 分别表示在空间
