Multi-Level Inverter For Domestic Application

Abstract

In this paper both DC-DC Converter and multilevel inverter have been proposed. The proposed multilevel inverter with appropriate gate signals generates seven level AC output voltage. Also, with the implementation of Low Pass Filter, the output voltage’s Total Harmonic Distortion is reduced. Not only switching losses but also voltage stress of switches can be reduced. With the help of Sinusoidal Pulse-Width Modulation (SPWM) switches of the inverters are controlled. Finally, a laboratory prototype has been implemented and from experimental results, the seven level output of implemented inverter can be inferred.
