Novo conversor multinível tipo-T com indutores divididos.

Abstract

A new T-type multilevel converter with split-inductors is proposed. It consists of replacing the traditional converter leg with the dual-buck structure, coupled with two split-inductors, which will limit the current variation, offering protection from current peaks during switching transients. An analysis of switching transients and the relationship between the existence of split-inductors and efficiency was carried out. Several comparisons between the use of high and low split-inductances were presented, as well as simulation results and experimental data to validate the proposed approach.
