380V直流給電システムにおける電源高出力密度化の一手法

抄録

A methodology for realizing a higher-power-density DC-DC converter has been proposed for a power unit installed in a 380-V DC distribution system. The possibility of the converter design will be strengthened by using the series-parallel connection topology for isolated DC-DC converters. A converter prototype with a power density of 10W/cm³ has been fabricated, and the feasibility of the converter design has been confirmed experimentally. This result contributes to the realization of a highly efficient and highly space-saving 380-V DC distribution system.
