摘要

The increasing requirements for enhancing power quality and capacity have driven the evolution of switched-capacitor multilevel inverters (SCMLIs). This paper introduces a novel 17-level SCMLI that achieves a quadruple voltage boost with a single DC source and reduced component count. The proposed design uses only three capacitors, three diodes, and ten switches, with capacitors maintaining self-balancing at steady-state voltage ratios of 1:2:0.5. The inverter demonstrates superior performance in terms of reduced Total Harmonic Distortion (THD) of 1.39% and improved efficiency. While the design is highly suitable for photovoltaic and renewable energy applications, limitations include its dependence on precise capacitor sizing and potential challenges in scalability for higher power systems. The primary objectives of this study are to reduce the component count, ensure high voltage boosting, and achieve inherent self-balancing, all of which are validated through comprehensive simulations. The outcomes include improved efficiency, lower THD, and a cost-effective solution for renewable energy integration. A detailed comparison with recently developed 17-level MLIs is performed based on number of components, gain and cost factor to confirm the superior design of the proposed circuit.
