说明：  在传统矩阵变换器和多电平逆变器的基础上,提出一种新颖的多电平矩阵变换器,介绍了其拓扑结构和工 作原理.多电平矩阵变换器的能量传递,是通过三相输入电压对中点电容充电到一个恒定直流电压而实现的.选择适 当的控制算法和电容电压,能在变换器的两侧合成低次谐波含量小且波形近似于正弦的可控输入/输出电压.对多电 平矩阵变换器进行建模和仿真,并探讨了其输出能控性. ( On the basis of a conventional matrix converter and a multilevel inverter, a novel multilevel matrix converter is proposed, and its topology configuration and principle are introduced. This converter operates as a bidirectional converter and transfers energy between its two sides by charging the midpoint capacitors to a known constant DC voltage level. Proper selection of control algorithms and capacitor voltages helps synthesize controllable and waveforms almost sinusoidal three-phases AC voltage with minimum low-order harmonics at both sides of the converter. The multilevel matrix converter is modeled and simulated with its output controllability discussed. )
