A dual voltage power supply for a vehicle is disclosed with a DC generator, a single storage battery, a low voltage load circuit including the storage battery and a high voltage load circuit including load devices designed to be powered by voltages higher than the battery voltage. A high voltage regulator is responsive to the generator output voltage and controls the energization of the field winding of the generator for causing the generator to produce an output voltage meeting the requirements of the high voltage load circuit. A low voltage regulator receives the output voltage of the generator and produces a substantially constant regulated voltage for charging the battery and supplying the low voltage load circuit.
