    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%.

    A conventional forward converter requires a transformer having an extra winding to assist in magnetic core reset, thus complicating the design and increasing the production cost. These shortcomings can be overcome by using an RCD clamp forward converter. This article presents a simplified analysis and design of the RCD clamp forward converter. The laboratory prototype is constructed. Experimental results demonstrates that the prototype converter is capable of providing a constant output voltage throughout its operating condition and has the maximum efficiency of 85%.
