Abstract

A novel Multi-level Inverter (MLI) with reduced Switched Capacitor (SC) is designed due to its aids of low component count and low-cost implementation. This paper introduces a novel SC-MLI to achieve increased number of output voltage levels with reduced component requirements. Henceforth, 13 level inverter is deployed using 14 switches, 3 capacitors and a single diode, in which voltage through capacitors is continued at required magnitude during the switching operation by utilizing Pulse Width Modulation (PWM) generator. By inducing 13 level reduced SC enables to attain improved voltage boosting with high voltage balancing ability thereby, providing better quality output to load. Thereby, the proposed approach concentrates on designing a reduced SC-MLI for achieving higher output voltage with desired output quality by utilizing very small number components, thereby reducing the size and cost of implementation. Furthermore, system is executed using MATLAB/Simulink and obtained result depicts that proposed system attained enhanced system performance with efficiency (98.50%) with increased amount of output voltage levels.
