摘　　要：分析了电压空间矢量PWM(VSVPWM)的基本原理,结合异步电动机变频调速,提出了一个 VSVPWM实现的新方法。该方法采用查表法来产生VSVPWM波,具有无须坐标转换、表格数据少、操作简单、运行速度快等优点。数字仿真及硬件电路实现结果证实了该方法的正确性和实用性。In this paper, the basic principle of Voltage Space Vector PWM is analysed, and combined with the principle of asynchronous motor variable frequency speed regulating, a new realizing method of voltage space vector PWM is presente. This method is based on the look-up-table algorithm. It does not is need to transform the coordinate, has less formed information, and it is easy to operate at a fast speed.The correctness and practicability of this method are confirmed by using the digital simulation and electrical circuits.
