摘要
根据多逆变器-电机推进系统的电路结构,应用戴维南等效定理,分析了环流的产生机理,得到并联逆变器推进系统的等效输出电路,从而可以简化控制系统设计。根据环流产生的机理,讨论了加均流电抗器和加环流反馈控制的环流抑制方法。
According to the motor circuit structure of a multi inverter, the paper analyzes the producing mechanism of circulation with Thevenin＇s theorem,and gets equivalent output circuit system for parallel inverter propulsion, which simplifies the design of control system. According to the mechanism of circulation,the paper also discusses restraining methods for the reactor and the circulation feedback control of circulating current.
