摘　　要：提出了一种 坐标系统,基于此坐标系,得到一种新的简化算法。对于任意阶电平数的逆变器而言,这种算法能够方便地判断出参考空间矢量所落入的扇区,非常容易地进行矢量的合成运算。最后提出和论证了 SVPWM 实质上是一种基于线电压的 PWM 技术。This paper proposes a kind of coordinates, based on which a new simplified algorithm can be obtained. For the inverters of the levels of any order, this algorithm can easily judge which vector the reference space vector falls in, and conduct the composition operations of the vectors. This paper verifies that the SVPWM algorithm is actually a PWM technology based on line voltage.
