Abstract

An improved self-driven active reset forward converter for low-voltage high-current applications is presented. The converter is derived from the operation of an active clamp forward. The suitability of the proposed converter for high frequency operation is illustrated. The advantages of the proposed converter in terms of simple drive requirements are explained. The converter is shown to exhibit reduced output ripple contents even with reduced output filter components. Experimental results are presented substantiating the operational features of the converter
