DESIGN AND ANALYSIS OF HIGH-EFFICIENCY STEP-UP INVERTER TOPOLOGIES USING SWITCHED CAPACITOR CONVERTERS

Abstract

The demand for efficient, compact, and cost-effective power conversion systems has driven significant innovation in multilevel inverter design. Traditional step-up multilevel inverters often require a large number of components, leading to increased complexity, higher cost, and reduced reliability. This study proposes a novel inverter topology that integrates switched capacitor converters to achieve high stepup voltage gain with fewer components. The proposed design reduces circuit complexity while maintaining high efficiency, improved voltage balancing, and reduced total harmonic distortion (THD). Simulation and experimental results validate the effectiveness of the topology, demonstrating superior performance compared to conventional designs in terms of power density, reliability, and cost-effectiveness. The findings highlight the potential of this innovative approach to advance modern renewable energy systems, electric drives, and smart grid applications, where efficiency and compact design are critical.
