Classification: H02J

Abstract:
A power supply system for supplying a battery voltage to a plurality of loads, comprising:an on/off signal generator circuit for generating an on/off signal;a plurality of power source units each supplying the battery voltage to an associated one of the plurality of loads in response to the on/off signal, each of the plurality of loads being associated with a single one of the plurality of power source units;a plurality of voltage detection circuits, each associated with one of the power source units, each voltage detection circuit supplying a voltage detection signal indicating whether the battery voltage is within an input voltage range of an associated one of the plurality of power source units; anda plurality of on/off signal transmitter circuits, each associated with one of the power source units, each on/off signal transmitter circuit selectively passing the on/off signal to an associated one of the plurality of power source units in response to a voltage detection signal from a voltage detection circuit associated with the associated one of the plurality of power source unit.
