Three-phase asymmetrical power source with power factor correction

This paper presents a novel technique to obtain asymmetrical output voltage from a three-phase power source in a single-stage. The goal is reached with the help of a three-phase power factor correction circuit. A possible application for this asymmetrical power source is to be implemented in the transition from 14 V to 42 V automobile electrical system. Design guidelines of the line inductors and duty cycles are established. Moreover, a detailed analysis of the proposed topology is developed. In addition, simulations and experimental results are shown for a 40 kHz switching frequency.
