A single phase nine level common ground switched capacitor inverter with double boosting capability
The proposed 9L7S‐CGSC‐TL inverter comprises of only seven switches, two diodes, three self‐balanced capacitors, and one DC source. The suggested inverter is having CG connection which eliminates ground leakage currents. Additionally, the suggested topology necessitates fewer conducting devices, thereby reducing conduction losses. Abstract This article
