A single phase nine level common ground switched capacitor inverter with double boosting capability
IET Power Electronics, Volume 17, Issue 16, Page 2900-2916, 16 December 2024.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
