Paper Abstract

Three different topologies for low voltage regulator modules are compared in this paper. A Push-Pull converter (PPC) equipped with a novel hybrid gating scheme, which supports synchronous and external driving is proposed and compared to a Two-Transistor Forward Converter (2TFC) with a simple enhanced gating circuit of the MOSFET based rectification. Finally, an asymmetrical driven Half Bridge converter (AHBC) with integrated magnetic components and synchronous rectifier (SR) supplements the comparison. This topology was discussed only recently with respect to the low voltage topic. Prototypes for three topologies were developed, operated at 48 V input voltage and deliver 1.7 V at 18 A output current.
