本文提出了一种基于输入相电压测量的直接三电平矩阵变换器（DTMC）的2/3/4/步换相策略。虽然自 21 世纪初以来人们就开始研究 DTMC，但尚未详细研究与直接矩阵转换器 (DMC) 换向的差异。添加的换向路径导致一组新的有限状态机 (FSM)，迫使电流流向滤波电容器的中性点电势。集中于输出电压的产生，将集中于中性点电势的换向，并且将扩展用于基于电压的换向的已知FSM。此外，还将讨论换向目标阶段短期变化的可用性。当 FSM 的输入数据在多步换向期间发生变化时，它们会变得有趣。分析了多步换相引起的输出电压偏差，并通过实验结果验证了其功能。
This paper proposes a 2/3/4/-step commutation strategy for direct three-level matrix converters (DTMC) based on input phase voltage measurement. While the DTMC is investigated since the beginning of the 21st century, the differences in the commutation to the direct matrix converter (DMC) has not been investigated in detail. The added commutation paths lead to a new set of finite state machines (FSM), which force the current flow to the neutral point potential of the filter capacitor. Concentrating on the output voltage generation, the commutation from and to the neutral point potential will be focused and the known FSM for voltage based commutation will be extended. Additionally, the usability of short-term changes in the commutation target phase, will be discussed. They become interesting when the input data of the FSM changes during a multi-step commutation. The output voltage deviation caused by the multi-step commutation will be analyzed and the functionality will be proven by experimental results.
