<P>PROBLEM TO BE SOLVED: To supply a stable power to a load element when electric power is supplied from a plurality of power supplies to the load element, even if a time lag occurs in a starting time between the plurality of power supplies. <P>SOLUTION: The power supply device comprises: the plurality of first power supplies DCDC 1, DCDC 2, in which a primary power supply voltage is converted into an intermediate voltage; second power supplies DCDC 3 to DCDC 7, in which the intermediate voltage converted by the first power supplies DCDC 1, DCDC 2 is converted into a supply voltage and output; and a timing adjustment part 20a which receives electric power converted into the intermediate voltage from the plurality of respective first power supplies DCDC 1, DCDC 2, adjusts the timing to absorb the time lag in the start timing of the plurality of first power supplies DCDC 1, DCDC 2, and allows the second power supplies DCDC 3 to DCDC 7 to output the supply voltage. <P>COPYRIGHT: (C)2009,JPO&INPIT |
