Abstract: In this paper a " Reduction of THD by Increasing the Levels of Reversing Voltage Multilevel Inverter Using PWM Techniques " is proposed. Because The Conventional Multilevel Inverters (MLI) required big wide variety of Capacitor, Diodes, input sources, electricity switches. So to reduce or overcome from this drawback MLI is used. In this paper an overview of a new multilevel inverter topology named reversing voltage is used. A Single phase 7-level topology is used to reduce the THD. This topology requires less number of components & less gate driver circuits as compared to conventional multilevel inverter topologies and avoids voltage balancing problems.

Keywords: MLI Simulation, Modulation Techniques, THD Comparison b/w No. of Components of Conventional & Proposed MLI.
