Abstract
Large high power electric drives and utility applications necessitate advanced power electronics converter to maintain high and medium power loads with proper modulation system. There are many multilevel inverter topologies familiarizing with as a substitute of high and medium power load. A multilevel inverter should achieve and progress both high power ratings and the better performance with an expected THD, power factor and efficiency. The cascade multilevel inverter is successfully the most possible topology for using as a power converter for medium and high power applications due to having PWM gate controlling of solid-state switches. It reduces disproportionately using of transformers, bulky capacitor and diodes which are mandatory element at several multilevel topologies. An equivalent MATLAB/Simulink model of proposed system is developed to investigate its performance. The proposed converter exhibits higher efficiency as compared to the conventional converter circuits.
