Implementation of a Novel Nine-Level Quadruple Boosting Inverter

Abstract

This paper proposes a novel nine-level quadruple-boosting multilevel inverter (MLI) that uses a single DC source and requires only ten power switches, one diode, and three capacitors. This design utilizes switched capacitors (SC) with a common ground (CG), achieving a four-fold voltage boost without needing an extra boost converter. The common grounding mitigates leakage current, making the system more efficient. In this proposed topology, the capacitors are self-balanced. The proposed inverter topology offers several advantages compared to existing nine-level inverters, such as significantly reducing leakage current due to common ground configuration, boosting capability, and using fewer components. MATLAB Simulink simulations demonstrate the superior effectiveness of the proposed nine-level quadruple-boosting MLI. © 2024 IEEE.
