摘　　要：基于对三相鼠笼式异步电动机变频转速控制的目的,在阐述SPWM输出原理基础上进行软件设计。采用规则采样法数学模型,通过查表法及相序延迟120°完成三相拟合,获得三相互补SPWM输出信号,所得三相互补SPWM输出信号可以驱动三相鼠笼式异步电机。Based on three-phase squirrel cage induction motor variable frequency speed control, the purpose of this article expounds the principle of SPWM output based on the software design. With the help of mathematical model of rule sampling method, the complementary three-phase SPWM output signal could be obtained through the look- up table method and phase sequence delay of 120 degrees. The complementary three-phase SPWM output signal can drive three-phase squirrel cage induction motor.
