Evaluation of Different Si/SiC Hybrid Three-Level Active NPC Inverters for High Power Density
TL;DR: Experimental results and analysis show that the full-SiC 3L-ANPC inverter has the highest efficiency, whereas the 2- SiC hybrid 3L -ANPC transformers has the best cost performance and better thermal balance characteristic.
