摘　　要：精简矩阵变换器RMC(reduced matrix converter)是一种新型的功率变换器,具有体积小、重量轻、转换级数少和可靠性高等特点,在电网与电动汽车互动等领域具有很好的应用前景。首先对精简矩阵变换器的拓扑结构进行了介绍,建立了数学模型;其次采用基于功率解耦的直接电流控制来实现能量双向流动,利用根轨迹法和Bode图对系统特性与稳定性进行分析,并对PI控制器进行设计;最后搭建RMC实验样机,实验结果验证了系统能够实现单位功率因数下的能量双向流动控制。A reduced matrix converter(RMC)is a novel type of power converter,which has characteristics such as small size,light weight,few conversion stages and high reliability.Therefore,it has a good application prospect in fields including electric vehicle-to-grid.In this paper,the circuit topology of RMC is introduced,and its mathematical model is established.The direct current control based on power decoupling is used to realize the bidirectional energy flow.At the same time,the characteristics and stability of the system are analyzed using the root locus diagram and Bode diagram,and the PI controller is designed.Finally,an experimental prototype of RMC was built,and experiment results confirm that the system can achieve the bidirectional energy flow control under unit power factor.
