An improved nine‐level switched capacitor‐based inverter with voltage boosting capability and limitation of capacitor current spikes for PV applications

To proceed to a net zero carbon world and mitigate the environmental challenges associated with it, integration speed of renewable energy sources such as photovoltaic (PV) systems has been increased around world. Here, an improved switched-capacitor based nine-level inverter is introduced for PV applications. This topology several benefits as, voltage boosting feature, using single DC source, reduction capacitor charging current spike extendable input voltage. produces output waveform power supply. topology, identical two capacitors in parallel can boost In this limit mode, inductor placed path diode. The losses overall efficiency analysis are considered. verify accurate performance under step change on flows, simulation results obtained by MATLAB/Simulink software presented. highlight inverter, comparison most recent topologies performed. Finally, feasibility experimental 770 W grid-tied prototype
