Abstract

In this paper the design and implementation of DC-DC converter based SMPS for a telecommunication system is presented. A high frequency transformer is used to provide the galvanic isolation between the input and output. A complete design methodology of high frequency transformer used for full-bridge buck derived topology is presented. The operating modes, analysis, and design considerations are explained for the proposed converter. Simulation and experimental results are also presented to demonstrate the performance of the proposed converter.
