A review and ultimate solution for output filters for high-power low-voltage DC/DC converters

Abstract

This paper revisits the selection of passive components for converters able to supply computer or telecom systems operated with 0.9 to 1.8V at 100s of Amps. Component selection is done from the available technology perspective rather than computation. Several low-cost (active or passive) improvements are suggested. Design is followed up with an example.
