Análisis y simulación de un convertidor ac-dc trifásico con alto factor de potencia y control por desplazamiento de fase

Abstract

This paper introduces a new switching mode power supply with the following properties: zero-voltage switching, Phase Shifted control approach at constant frequency, three-phase input current with high power factor and low harmonic distortion. Operation and description of the circuit, theoretical analysis and simulations results, on a 1.5kW, 20kHz and 60V output three phase AC - DC converter are presented, which confirm the performance of de proposed topology.
