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 switch-mode converter from dual-input-voltage operation (230 V_rms, 50 Hz/115 V_rms, 60 Hz). For European line voltages (220, 230, and 240 V), the full-bridge rectifier complies with the IEC-61000-3-2 class A standard, if the value of the capacitor is selected with the right criterion. 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 good agreement between experimental results and the mathematical analysis predictions.
