“…By observing the Fig. 6, it is verified that the waveform of the equivalent output voltage for the 5L-NPC-IC inverter using uncoupled inductors is identical to the waveform of the output voltage V AO for the 5L-NPC-MSSC inverter [11]. By comparing the equivalent output circuits for the two converters, it is concluded that (1) must be satisfied.…”

“…From the values of the currents through the semiconductors, calculated based on the equations presented in [11], the conduction and switching losses for a single switch are calculated in accordance with (10) and (11) The switching losses in S 2 , S 3 , S 6 and S 7 are nearly zero due to the low switching frequency of the switches. The total losses for a single switch are calculated by adding the respective conduction and switching losses.…”

“…A análise do inversor de cinco níveis (5N) NPC-CCME, que utiliza um autotransformador, foi realizada em [11], sendo verificado o funcionamento deste conversor através de resultados experimentais. Entretanto, estas topologias necessitam de uma avaliação de desempenho adequada no que se refere ao número de interruptores, volume dos dissipadores e dos componentes magnéticos, DHT da tensão de saída, densidade de potência e rendimento de cada conversor.…”

“…Verifica-se que as três topologias apresentam o mesmo número de semicondutores. Para os inversores de cinco níveis NPC-CCME e NPC-CCI, os sinais de comando dos interruptores correspondentes de cada braço estão defasados de 180º [11]. Para o inversor de três níveis NPC-PCC, os respectivos sinais estão em fase.…”
