PWM逆变器驱动异步电动机的稳定性分析和控制

Stability Analysis and Control of Asychronous Motor Driven by PWM Inverter Cui Jianming,Wu Xinghua (College of Electrical & Power Engineering of TUT)

在文献［１］研究的基础上，又对ＰＷＭ逆变器的“死区效应”进行了分析，认为误差脉冲电压和定子电阻都是影响异步电动机稳定运行的原因，为此，设计了一种控制电路，通过实验，证实了分析的正确性。

Based on the study shown in referece material and analyzed the “dead zine effect”of PWM inverter,it was considered that error pulse voltage and stator resistance both are the influencing reasons for the steady operation of asychronous motor,as a result a kind of control circuit was designed and the correctness of the analysis was proved by experiment made.
