模块化多电平谐振DC/DC变换器的固定频率K+2D调制以实现全子模块ZVS运行

Modular multilevel resonant dc–dc converters (MMRDCs) are increasingly recognized as competitive solutions for medium-voltage to low-voltage (MV-LV) conversion with wide input ranges. However, these systems often face challenges of low conversion efficiency due to the inability to achieve sufficient soft-switching or excessive conduction loss. This article proposes a novel fixed-frequency K+2D con...
