Active Front End Topology Based Three Phase Inverter

End (AFE) topology based three-phase inverter are presented in this paper. The inverter belongs to Infinite Level (ILI) Multi-level Inverters (MLI) with Reduced Switch Count. The circuit consists of three dc to dc buck converters connected to the individual legs of the six switch three-phase inverter. Three phase output is obtained at the output of the inverter without any external filtering circuit. The dc bus utilization is also improved by using third harmonic injection. The three-phase induction motor is considered as load and performance is evaluated for full load conditions. AFE based ILI reduces the switching and conduction losses as only one switch is switching at high frequency per phase.
