Single Phase Hybrid Cascaded H-Bridge and Flying Capacitor Multilevel Inverter with Capacitor Voltage Balancing

This research suggests a single-phase hybrid cascaded H-Bridge & Flying capacitor multilevel inverter featuring capacitor voltage balancing. Main multilevel inverter topology comprises flying capacitor as well as the cascaded H-Bridge. While cascaded H-bridge multilevel inverters may use a single DC source, flying capacitor multilevel inverters' capacitors need internal voltage balancing. To this end, a hybrid-topology inverter is developed by connecting the outputs of a single-phase five-level flying capacitor & 5-level cascaded H-bridge inverter in series. This method gives fast and good control with minimum acceptable amount of harmonics. In MATLAB/Simulink software the proposed methodology is being designed
