| Abstract |
Contactless DC connector has been proposed for high power density 380 V DC power feeding system. A LLC resonant DCDC converter topology with GaN power transistors and SiSBDs has been applied to realize high frequency and high efficiency inductivelycoupled contactless DC connector. ISOP (input series and output parallel)IPOS (input parallel and output series) connection topology has been also employed to develop 380 V DC connector. Prototype of a 1.2 kW 384 V192 V DC connector to constitute a part of 384 V384 V connector has been fabricated, and maximum efficiency of 96.5\% with the ideal power density of 5.4 W/cm3 has been confirmed experimentally under 500 kHz operation. Design consideration for the proposed connector has been also conducted, and the approach for achieving higher power density of 10 W/cm3 has been presented. |
