<P>PROBLEM TO BE SOLVED: To provide a power supply system with which it is possible to improve reliability while increasing the maximal value of a current that can be supplied to an on-vehicle load 28 or the like. <P>SOLUTION: A power supply system supplies power to an on-vehicle load 28 or the like by means of a parallel connection body of a master DCDC 12a and a slave DCDC 12b. Here, a target voltage of the master DCDC 12a is higher than that of the slave DCDC 12b. Also, the master DCDC 12a and the slave DCDC 12b have constant current drooping characteristics. In this construction, when an output current of the slave DCDC 12b exceeds a prescribed value, processing is performed to increase a limit value of an output current of the master DCDC 12a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
