Opis

Multilevel inverters are playing a major role in PV based systems because of numerous advantages like low dv/dt, better harmonic profile so on. But, conventional multilevel inverters consist of some drawbacks like capacitor voltage balancing issues in neutral point clamped multilevel inverter and flying capacitor multilevel inverters. Moreover flying capacitor multilevel inverters requires more number of capacitor banks and neutral point clamped multilevel inverters require more number of clamping diodes. If any one switch of conventional multilevel inverter (NPC or flying capacitor) fails, the entire configuration has to be shutdown. To address these issues, a novel multi-level inverter has been proposed in this project which can be operated during the failure of any power electronic switching device / isolated dc source.
