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

Selective harmonic elimination in PUC‐5 multilevel inverter using hybrid IGWO‐DE algorithm

Engineering Reports, Volume 6, Issue 10, October 2024.
The inverter switching can be done at a low frequency using the Selective Harmonic Elimination (SHE) technique, and the unwanted harmonics can be significantly reduced; however, the issue with SHE is solving the transcendental equations and determining the optimum switching angle.
