Design and Experimental Verification of an Integrated Boost-Flyback Converter with Voltage Multiplier

This paper introduces the design and experimental validation of an integrated boost-flyback converter with a voltage multiplier (IBFCVM). It describes the operation of the IBFCVM and provides its essential voltage and current equations. A phototyped circuit design for a 72W, 12V-to-120V IBFCVM is presented. Experimental results demonstrate that the proposed IBFCVM exhibits effective output voltage regulation, achieving an impressive efficiency of 89.9%.
