SWITCHED INDUCTOR QUASI Z-SOURCE INVERTER FED INDUCTION MOTOR DRIVE WITH REDUCED THD

Abstract

This paper proposes a reduction of harmonics in source current and load current of Switched Inductor Quasi Z Source Inverter fed Induction Motor Drive. An EMI filter is suggested at the input to reduce the Harmonics in the source current and a three phase LC filter is proposed at the output to reduce the load harmonics. The simulation results of the existing system and proposed system are presented to study the reduction in the harmonics.
