This paper presents the analysis and design of a single-phase, high-power-factor rectifier module to be integrated in a three-phase modular architecture for avionic applications. The target is an aircraft fuel pump drive, where the rectifier feeds the voltage source inverter (VSI) connected to the pump's electrical motor. The proposed topology, based on isolated SEPIC submodules with a regenerative snubber, can withstand a line frequency variation from 250 Hz to 800 Hz, as well as a 70 - 180V line RMS voltage range. Experimental results are taken on a 270V-1500W module prototype.

Abstract
This paper presents the analysis and design of a single-phase, high-power-factor rectifier module to be integrated in a three-phase modular architecture for avionic applications. The target is an aircraft fuel pump drive, where the rectifier feeds the voltage source inverter (VSI) connected to the pump's electrical motor. The proposed topology, based on isolated SEPIC submodules with a regenerative snubber, can withstand a line frequency variation from 250 Hz to 800 Hz, as well as a 70 - 180V line RMS voltage range. Experimental results are taken on a 270V-1500W module prototype.
