| 摘 要： | 为解决传统空间矢量脉宽调制(SVPWM)算法计算复杂的问题,提出一种改进的SVPWM算法,仅需根据输入的三相参考电压便可以快速确定参考电压矢量所在扇区并得到基本电压矢量作用时间的统一计算式,无需任何复杂的坐标变换、三角函数计算,编程简单,与传统SVPWM算法相比具有更好的实时性。通过仿真与实验验证了该算法的有效性。

| Abstract: | An improved SVPWM algorithm is proposed. Both sector and uniform vector duration formulae can be confirmed only according to the input three-phase reference voltage. It needs on any complex coordinate transformation, trigonometric function computation, is simple to programming and has better real-time. The validity of the proposed algorithm is demonstrated by the simulation and experimental results. |
