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.
