This work presents a comparative evaluation of three single-phase neutral point clamped multilevel inverters, based on switching cells, which have as a common characteristic the capacity increase of the total output current of the converters without increasing the current efforts in semiconductors. The technique employed to perform this evaluation consists primarily on individual analysis of the classical three level topology, applying only the parallelism of switching cells. Then a detailed analysis of the main topology evaluated in this work is performed. It is the five level neutral point clamped inverter, based on multi-state switching cell, which uses multilevel interleaved converters, coupled magnetically through an autotransformer in...
