In a replenishing power supply system, a plurality of DC/DC converters ( 5, 6 and 7 ) are connected in parallel, and the number of DC/DC converters ( 5, 6 and 7 ) to be started is changed based on the amounts of electric power used by auxiliary loads ( 11 and 12 ). Moreover, the DC/DC converters ( 5, 6 and 7 ) are started in order based on a predetermined sequence. |
