This paper describes a study aiming at build of back to back (BTB) system for the test of high power DC-DC Converter. The proposed new BTB system for test circuit offers the solutions in the reduction of the capability of input power source and bidirectional operational mode test at rating condition. This time we built 20 kW BTB system actually and tested it by 100 kW DC-DC converter. We report the...
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...
