Abstract

A modified series-parallel high-frequency resonant DC/DC power converter configuration suitable for 48 V output is proposed. A simplified steady-state analysis using complex circuit analysis is presented. Based on the analysis, a simple design procedure is given. Detailed experimental results obtained from a MOSFET-based 1 kW converter are presented to verify the analysis. The converter presented has almost constant efficiency from full load to quarter load. The variation in switching frequency required to regulate the output voltage constant is narrow, and the converter has load short-circuit capability
