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...
PEM fuel cell is a clean and high-efficient generation, which can be applied widely. Oxygen concentration of cathode reactants plays an important role on its performance. Performance of PEM fuel cell was surveyed by experiments in this paper. Influence of oxygen concentration on performance of PEM fuel cell is studied. Experimental results show that with the increase of oxygen concentration, open...
