Abstract
Photovoltaic-based switched capacitor-fed multilevel inverter for increasing the on the whole performance of the inverter, and increasing the voltage gain of the inverter has been presented in this paper. This system achieves the PV-based MPPT method and makes the steadiness between the source and load and also provides the desired power to the load. The intend of this paper is to replace the conventional-type multilevel inverter by a new method that can produce the number of voltage levels with low quantity of gate drivers and power supply. A new configuration is switched capacitor-fed multilevel inverter (SC-MLI) which can enhance the output voltage level than the input voltage by placing the capacitor with a reduced switch count. As a result, the overall cost of the inverter switches is compact. This study compares the harmonic reduction in the existing cascaded multilevel inverter (CHB) with proposed switched capacitor-fed five-level inverter (SC-MLI) using PWM technique. The proposed methodology with decrease in switch count in switched capacitor multilevel inverter has been implemented. In this paper, circuit, scrutiny and simulation results are exposed and verified using MATLAB/Simulink.
