<p>A power distributing system is provided with improved efficiency in converting a voltage of a power source and also reduced heat-generation. The power distributing apparatus 1 includes a power source part 4 generating a power source of a high voltage and a plurality of electronic control units 7 to which the power source part 4 supplies the power source of the high voltage through respective power lines 5, 8. The power lines 8 from the power source part 4 are connected with the electronic control units 7 through the intermediary of a plurality of intermediate connectors 9. Each intermediate connector 9 has a built-in converter 13 for converting the high voltage of 42V into an intermediate voltage of 12V. In each electronic control unit 7, a series regulator 14 is arranged to convert the intermediate voltage of 12V into a load voltage of 5V.</p> |
