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. |
