High Gain DC-DC Boost Converter with Enhanced Capability for Non Conventional Energy Application

This study presents a novel DC-DC boost converter that employs a switched-capacitor cell-based topology to raise voltage levels. By integrating a voltage multiplier circuit, the converter achieves higher efficiency compared to conventional boost converters while requiring fewer components. It effectively mitigates stress on capacitors, diodes, and semiconductor switches, resulting in a high voltage gain with a low duty cycle. The converter is designed to support continuous source current and enables ground-sharing capabilities between the input and output sides, making it well-suited for renewable energy applications. The study examines the converter’s performance in detail, including comparisons between comparable configurations, power loss estimations, and steady-state assessments. Matlab/Simulink outcomes are compared to standard topologies, and theoretical analysis indicates an efficiency of 91% at 50 W. Overall, the efficiency of this novel DC-DC boost converter outperforms that of traditional converters and provides significant advantages for a wide range of applications.
