Three Phase Five Level T-Type Multi Level Inverter using Hybrid Sources

Abstract

This paper presents a 5 level T-type multilevel inverter, to improve the performance of the hybrid system and then improved voltage is injected into the grid. Two three level inverter with common emitter and common collector configurations are combined to obtain a five level inverter. PV and wind energy is used as a source of energy to the five level T-type MLI. It has advantages such as low switching losses, lesser THD, less filter requirement and superior output quality when compared to 3-level T-type MLI. PWM technique is employed to generate output voltage. The Simulation is done using MATLAB Simulink.
