Year: 2025

Type: article

Abstract: Switched-capacitor (SC) multilevel inverters (MLIs) are widely used in a variety of applications due to their ability to boost voltage and balance capacitor voltage. High efficiency inverters with high boosting leads to inverters with higher component count and lower efficiency. This article proposes a seven-level active neutral point clamped-based SC inverter with a boosting of 1.5. The proposed topology, which includes six switches, and six diodes, produces a seven-level output voltage with an efficiency of 98.4%, and voltage and current THD% of 22.27% and 10.67%. This article also suggests integrating Level Shifted (LS) PWM with Phase Shifted (PS) PWM. The amalgamation enhances the converter's overall efficiency by lowering switching losses by combining the benefits of both switching technologies. The reliability of the proposed inverter has also been analysed. The simulation as well as hardware results have been presented to validate the performance of the proposed inverter.
