<p>PROBLEM TO BE SOLVED: To provide a uniform degree of variation of each output voltage when causing a plurality of DC-DC converters to output the same output voltage level.SOLUTION: A power control device 2 includes: a first DC-DC converter 21 for generating a predetermined reference voltage V1; a power unit 20 for outputting a predetermined power voltage Vin; and one or a plurality of second DC-DC converters 22 for inputting the reference voltage V1 and the power voltage Vin, and for inputting an output voltage V2, which is output earlier and is fed back, to generate the output voltage V2, having the same level as the reference voltage V1, from the power voltage Vin, on the basis of a voltage difference Ve between the reference voltage V1 and the output voltage V2 fed back.</p> |
