A New Topology of Cascaded Multilevel Inverter with Single Dc Source

Abstract

Multilevel inverters have become more popular in electric high power and medium voltage applications due to fewer disturbances and obtains the quality power. This paper presents a new topology of a multilevel inverter with single DC source and high frequency cascaded transformers to reduce the harmonics and obtain a high output voltage from less input voltage. The proposed topology uses Voltage Source Inverters, which are controlled by using Carrier Based Phase Shift PWM technique. Simulation and Comparison can be studied using MATLAB/SIMULINK for the proposed inverter and other topologies.
