Triple boost switched capacitor multilevel inverter (TB‐SCMLI) with reduced components and self‐voltage balance

IET Power Electronics, EarlyView., 2023
The proposed TB‐SCMLI is able to provide seven levels of output voltage by balancing the voltage of two capacitors with the given control logic. The various SCMLIs are evaluated to determine the contribution of the suggested TB‐SCMLI topology's merits and downsides.

An assessment of H‐bridge less grid‐tied multilevel inverter with minimum device count and lesser total standing voltage

IET Power Electronics, EarlyView., 2023
An innovative switched‐capacitor‐based inverter is proposed in this article. The suggested converter can produce a five‐level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The effectiveness of the suggested inverter is verified by experimental results using hardware in loop OPAL‐RT OP4510.
