Design of Multilevel Multicarrier H-Bridge Inverter fed Induction Motor Drive

Abstract

The design of H-Bridge Multilevel-multicarrier inverter fed variable frequency drive is discussed. A nine level inverter is proposed to drive a half hp induction motor. Simulation studies carried out on Single phase and three phase inverters using Simulink/MATLAB. The results are compared with a hardware module of single phase multi carrier inverter. The design aspects of three phase multicarrier inverter including the transformer design are presented in this paper.
