Abstract

This paper presents two approaches to semiconductor power loss analysis in Modular Multilevel Converters (MMC) controlled without feedback of the switching cell capacitor voltage. The first one is a novel analytical approach - basing on an averaged model of the MMC. The second one is basing on detailed model in Matlab-Simulink - used as a reference for the analytical one. Analyses are performed for five MMC switching cells scenario. The analytical method has been proven as sufficient and fast solution for the MMC power losses estimation.
