Abstract :
This paper introduces a new switching mode power supply with the following properties: zero-voltage switching; pulse-width modulation at constant frequency; three-phase input with high power factor; and low input current distortion, using a single power stage formed by a full-bridge DC to DC power converter. Circuit operation, theoretical analysis, simulation, and design procedures and examples are presented. A laboratory prototype rated at 1.5 kW and operating at 100 kHz has been fabricated and tested successfully. The corresponding experimental results are included in the paper
