摘　　要：模块化多电平矩阵变换器(M3C)作为一种新型拓扑具有诸多优点,但其控制变量较多、控制结构复杂。文中首先对M3C系统的工作原理进行了分析,并建立了其数学模型;在此基础之上,分析并研究了M3C系统的输出电压和电流、桥臂电流、桥臂能量均衡、桥臂子模块电容电压等电气参量的控制策略,同时给出了M3C系统交流侧电压、电流的输入、输出整体控制策略,以实现M3C的稳定运行,且具有较好的动、静态特性。最后,通过建立M3C系统结构的仿真模型及实验平台对控制方法进行仿真和实验,验证了M3C系统控制策略的可靠性及稳定性。Modular multilevel matrix converter(M3C)as a new topology has many advantages,but it has many control variables and complicated control structure.Firstly,the working principle of M3C system is analyzed,and its mathematical model is established.On this basis,the control strategy for voltage and current output,bridge arm current,bridge arm energy balance,and the voltage balance of bridge arm sub-module capacitor are analyzed and investigated.The overall control scheme of voltage and current both at the input and output of AC side of M3C system are also given to achieve the stable operation with good dynamic and static characteristics.Finally,M3C system structure simulation model and experimental platform are established,and the control method is simulated and experimentally verified,which verifies the reliability and stability of M3C system control strategy.
