基于梯形调制MMC的高功率DC-DC变换器分析与设计

The modular multilevel converter (MMC) based dc–dc converters (MMDCs) are essential for voltage matching, galvanic isolation, renewable integration, and other applications in high voltage direct current systems. The trapezoidal modulation in these converters has been a proven advantage owing to reduced capacitive requirement and high power density. However, the existing short overlap (SO) trapezoi...
