Abstract

This paper presents a phase shifted full bridge (PSFB) DC/DC converter with current doubler synchronous rectifier for auxiliary power units (APU). The proposed converter is suitable for low output voltage with high output current applications like APU. A zero current switching (ZCS) control scheme is proposed to reduce MOSFET body diode conduction loss of synchronous rectifier. The proposed control scheme is verified by experimental results with a 1200W, 100 kHz prototype.
