Abstract

A Resonant AC/DC Converter for High Frequency Power Distribution Systems is presented in this thesis. The proposed converter employs a resonant network consisting of a few passive components. With this resonant network, the converter can attain close to unity power factor and very small total harmonic distortion under all load conditions. The operating principle of the circuit is demonstrated, and the steady state analysis is performed including the effect of leakage inductance. Based on the analysis, criteria for optimal design are given. Experimental and simulation results of a prototype converting the input AC voltage of 28 V rms at 1 MHz, to 1.6 Volt DC at 20 A are given to verify the proof of concept, and analytical work reported in this thesis.
