Retificador Unidirecional Multinível com Regulação Automática das Tensões

Multilevel rectifiers allow improving the system performance by reducing harmonic content of synthesized voltages, which leads to minimizing size and weight grid interface filters. Alternatively, use unidirectional PWM is particularly interesting in situations where there nonregenerative operation, since it possible operate with fewer active switches. This work proposes a five-level rectifier reduces number components needed allows automatic regulation floating capacitors without employing complex control techniques sensors and/or additional circuits. In addition, proposed requires devices lower reverse voltages and, consequently, series can be minimized. Simulation results demonstrate validity proposal.
