Nos geradores de energia renovável, devido ao alto custo inicial e ao ciclo de trabalho dos sistemas, o parâmetro de eficiência ocupa um lugar importante. Por esta razão, os inversores multiníveis controlados por frequência de linha são uma das escolhas mais adequadas para conversores de energia renovável. Entre estes, as estruturas de inversores multiníveis com fixação por diodo são um dos inversores mais importantes e mais eficientes. Neste artigo, um circuito equivalente simples com diodo fixado por diodo para explorar a eficiência sob cargas resistivas é proposto e, com base neste circuito simples, é analisada a dissipação de potência no estado em um inversor multinível com diodo fixado por diodo melhorado e original sob cargas resistivas. Em seguida, equações comparativas de eficiência são extraídas para inversores que usam transistores de efeito de campo semicondutores de óxido metálico (MOSFETs) e outras junções pn como chaves. Essas equações nos permitem ter uma ideia melhor de como conduzir a dissipação de potência em diodos fixados e nos ajudam a escolher chaves apropriadas para ter uma menor dissipação de potência no estado. Alguns casos são estudados e ao final fica comprovado que a eficiência calculada sob carga resistiva é um limite para carga indutiva com a mesma impedância em inversor fixado por diodo com chaves de junção pn. Isto significa que calcular a eficiência sob cargas resistivas nos permite prever aproximadamente a eficiência sob cargas indutivas.

Abstract: In renewable power generators, because of high initial cost and duty cycle of systems, efficiency parameter has an important place. For this reason, line frequency controlled multilevel inverters are one of most proper choices for renewable power converters. Among these, diode-clamped multilevel inverter structures are one of most important and best efficient inverters. In this paper, a simple diode-clamped equivalent circuit for exploring the efficiency under resistive loads is proposed, and based on this simple circuit, the on-state power dissipation in improved and original diode-clamped multilevel inverter under resistive loads is analyzed. Then, comparative efficiency equations are extracted for inverters that use metal oxide semiconductor field-effect transistors (MOSFETs) and other p-n junction as switches. These equations enable us to have a better idea of conducting power dissipation in diode-clamped and help us to choose appropriate switches for having a lower on-state power dissipation. Some cases are studied and in the end it is proven that the calculated efficiency under resistive load is a boundary for inductive load with the same impedance in diode-clamped inverter with p-n junction switches. This means that calculating the efficiency under resistive loads enables us to approximately predict efficiency under inductive loads.
