Abstract

This paper introduced a new soft switching scheme QRAS (quasi-resonant regenerating active snubber) converter aimed for the fuel cell electric vehicle (FCEV). The QRAS offers a simple structure resulting in economical and reliable power converter for the FCEV. Furthermore, the QRAS operates in high efficiency and high power. For confirming the practical effectiveness and novelty of the QRAS, the one-tenth prototype model was actually tested at the 8 kW rating. The circuit geometry, the basic operation, the 8 kW one-tenth-prototype test results were verified successfully. In addition, the preliminary evaluation of efficiency rise using "silicon carbide (SiC)" power devices is given with successful experimental results
