ABSTRACT:
A power distributing apparatus is provided to reduce the number of voltage converters. The power distributing apparatus1includes a power source part4for supplying a power of 42V, an electrical connection box7connected with the part4through a power line5,and a plurality of electronic control units8a, 8b. . . , 8n. The electrical connection box7has a regular-supply converter9to convert a high voltage of 42V to an intermediate voltage higher than a load voltage of 5V. The regular-supply converter9can exhibit a high conversion efficiency when the apparatus is operated under high load. Each of the electronic control units8a, 8b. . . , 8nhas a series regulator14to convert the intermediate voltage to the load voltage. Owing to the supply of voltage higher than the load voltage by the regular-supply converter9,there is no need to consider inconvenience due to voltage drop between the converter and a remote load.
