采用准两电平运行方式减小钳位二极管体积的SiC三电平中点钳位变换器

Medium voltage SiC mosfets have recently garnered considerable attention in the medium-voltage high-power areas like high-frequency solid-state transformers and multilevel converters. While direct series connection of these mosfets is an option for higher voltage levels, it requires complex voltage balancing approaches for device voltage balancing during fast switching transients. Alternatively, c...
