一种采用梯形调制的新型混合多电平DC-DC变换器

This article presents a new hybrid multilevel converter for medium voltage dc–dc interconnection. The structure of the topology is a hybrid of two-level converter and the modular multilevel converter (MMC). The proposed converter provides three-phase trapezoidal output voltages with a controlled slope while using only a single MMC leg. Therefore, using fewer submodules and sensors, and with its fe...
