摘　　要：为减少异步电动机变频调速时逆变器输出波形的谐波,提高电机效率,在分析了PWM(Pulse Width Modulation)型逆变器电压谐波对电机性能影响的基础上,提出了其波形的优化方向。To reduce the harmonic wave components of the PWM converter output wave when asynchronous motors frequency control is applied and to improve the efficiency of the motors, the direction on how to optimize the voltage wave is proposed based on the analysis of the influence of harmony wave components of the PWM converter voltage on the performance of the motors,
