| 摘 要： | 研究了基于双频的三相桥式逆变器拓扑结构,该拓扑由两个传统的三相桥式逆变器级联而成,其中一个工作在低频状态,另一个工作于高频状态,两单元功能相对分离。对高频单元采用单周控制,对低频单元采用电流滞环控制,利用Matlab/Simulink建立了仿真模型。仿真结果表明,该拓扑对降低开关损耗、电流总谐波畸变率、提高系统响应速度具有很好的作用。

| Abstract: | Three-phase bridge inverter based on dual frequency is researched,which is cascade connected by two traditional three-phase bridge inverter.One works in the low-frequency state,the other one works in the high-frequency state,the functions of those two units are relatively separated.In this paper,one-cycle control is adopted to the high-frequency unit while the low-frequency unit is hysteresis current control.Matlab/Simulink is applied to establish a simulation model.The simulation results show that the typo... |
