A contactless DC connector concept has been proposed for next–generation 380–V DC distribution systems in data centers. An LLC resonant DC–DC converter topology with gallium nitride (GaN) power transistors has been applied to realize a highly efficient inductively coupled contactless connector. A prototype of a 1.2–kW 384 V–192 V contactless connector has been fabricated. An efficiency of over 95% and an ideal power density of over 5.0 W/cm3 have been confirmed experimentally under 500–kHz operation. Design considerations for the proposed connector have been also conducted, and the approach for achieving a higher power density of 10 W/cm3 has been presented. The proposed concept contributes to realizing a high–power–density DC distribution system because the functions for both the isolated DC–DC converter and conventional connector are integrated in a single instrument.
