摘　　要：有效地利用过调制控制策略,能够提高逆变器的输出电压,对提高电动机的动态响应速度和扩大稳定运行区域具有重要意义。主要研究了过调制产生的原因,总结了几种典型的过调制控制策略,讨论了它们各自的优缺点,并指出了现有过调制控制策略中存在的问题。Utilizing overmodulation strategies effectively can improve the inverter output voltage, which is useful for improving the motor dynamic response and extending the stable operation region. The production of overmodulation was analyzed. Several classical overmodulation strategies were summarized, then their advanta- ges and disadvantages were discussed respectively. Finally problems of the existing overmodulation strategies were pointed out.
