Abstract

The aim of this paper is to present a theoretical and practical analysis of one of the most popular AC-DC converter topologies. This topology is used to feed a DC-DC switchmode converter from dual input voltage operation (230 V/sub rms/, 50 Hz/115 V/sub rms/, 60 Hz). Simple expressions are obtained for all RMS and peak currents and voltages, the mathematical analysis of this multifunctional AC-DC converter becomes very simple if the suitable assumptions are made. There is a good agreement between experimental results and the mathematical analysis predictions.
