提出了一种基于低频三电平中点箝位变换器和高频级联H桥变换器的新型混合多电平逆变器，用于高压直流输电。这种结构可以充分利用传统的硅基功率器件和新一代的碳化硅基功率器件来制作高压电压源逆变器。与模块化多电平变换器相比，该拓扑可以减小功率开关的体积和数量。最后，给出了调制和控制策略，并通过全尺寸仿真系统和小型实验平台进行了验证。
A novel hybrid multilevel inverter based on a low‐frequency three‐level neutral‐point‐clamped converter and high‐frequency cascaded H‐bridge converters for high‐voltage direct current transmission is presented. This structure can make full use of traditional silicon‐based power devices and a new generation of silicon‐carbide‐based power devices to fabricate a high‐voltage voltage source inverter. The topology can reduce the volume and number of power switches as compared with a modular multilevel converter. Finally, the modulation and control strategies are presented, which are verified by a full‐scale simulation system and a small‐scale experimental platform.
