High Gain Switched-Capacitor Multilevel Inverter

In modern days the demand for electricity is high, and as non-renewable energy sources account for the majority of their production currently, this need is rising quickly. energy resources will satisfy increasing power demand and essential energy needs; among several forms of renewable energy the easiest and most convenient energy source out of all those present. For utilizing solar energy for the generation of electric power solar photovoltaic technology is used. the power quality issues are more with the conventional inverters, and high voltage and high power handling power electronic switches are required for constructing the inverters. Multilevel inverters are the best in mitigating output voltage Total Harmonic Distortion (THD) and voltage strain on the devices also gets reduced. The output voltage profile is not much deviate from a sinusoidal voltage like a square wave inverter output voltage or two-level a converter's output. Due to the small voltage step increments in multilevel inverters, the dv/dt stress on the switching devices is decreased, reducing electromagnetic compatibility (EMC), when operated at high voltage, semiconductor devices with lower ratings had better output voltage characteristics. Due to their high gain, switched capacitor multilevel inverters are receiving a lot of interest, fewer switches usage, and low voltage stress, etc., A suitable control scheme will be designed to drive various switches in the Switched capacitor multilevel inverter. The project is mainly focused on the development of a switched-capacitor multilevel inverter topology with reduced switch count for renewable energy applications and to improve power quality. The described switched capacitor multilevel inverter will be simulated on MATLAB/SIMULINK environment and simulated results will be validated with theoretical proofs.
