ABSTRACT:
A highly reliable and low cost power supply unit for vehicles is provided which allows the control operation of a high voltage load controller to be carried out easily. When electric power is supplied from a generator 1A to a high voltage load 5, a change-over relay 4A is switched so that a battery 6a is connected to the high voltage load 5 to excite a field winding 12 of the generator. A first diode 21 and a second diode 22 are provided so that when the electric power generated by the generator the current generated by the generator is prevented from flowing into a vehicle system voltage load 6 including a battery 6a.
