Abstract

This paper proposes a switched-mode power supply (SMPS) with power factor correction. A preregulator boost converter is employed in order to obtain universal line voltage and reduced harmonic content of the input current. Two dc/dc forward converters are used so that two symmetrical output stages are obtained. The association of the aforementioned ac/dc and dc/dc converters results in a high power factor SMPS.
