Abstract :
A series of multiple output, 500 Watt, dc-dc converter boards for use in a 3kW computer power system is described. High power-density (9 Watts/cu.in. including heatsinks) is achieved through the use of thick film hybrid modules and a 316kHz switching frequency. The system considerations, design tradeoffs, and problems encountered are described. Future considerations for further enhancements to performance are proposed.
