非接触式DC连接器概念已被提出用于数据中心中的下一代380-V DC配电系统。采用氮化镓功率晶体管的LLC谐振DC-DC转换器拓扑结构实现了高效的电感耦合非接触式连接器。制作了一个1.2kW的384 V-192 V非接触式连接器样机。在500 kHz的工作频率下,实验证实了效率超过95%,理想的功率密度超过5.0 W/cm ~ 3。还对所提出的连接器进行了设计考虑,并提出了实现10 W/cm 3的更高功率密度的方法。所提出的概念有助于实现高功率密度直流配电系统,因为隔离式DC-DC转换器和传统连接器的功能都集成在单个仪器中。
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.
