Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power supply device and a control method for the same that prevent power that charges a secondary battery from exceeding an input limit of the power.SOLUTION: When a determining power value Pj that is the sum of motor power values Pm1 and Pm2 consumed or generated in motors MG1 and MG2 and capacitor power values Pc to charge and discharge a high voltage system smoothing capacitor is less than a value obtained by adding a margin α1 to an input limit Win of a high voltage battery, and a high voltage system voltage VH is less than a value obtained by subtracting a margin β from a maximum boostable voltage Vmax, a targeted voltage command value VH* of a high voltage system power line is corrected to the maximum boostable voltage Vmax (S130 to S160). A high voltage system smoothing capacitor 65 is charged by increasing the high voltage system voltage VH to the maximum boostable voltage Vmax, whereby, by increasing the determining power value Pj (decreasing its absolute value), power that charges the high voltage battery can be prevented from exceeding the input limit Win.
