PROBLEM TO BE SOLVED: To provide a vehicular power supply device capable of appropriately correcting a shift of an actual motor rotation position from a motor rotation position detected by a detection device in a vehicle having functionality of intermittent step-up control.SOLUTION: A control apparatus 500 controls a step-up converter in a continuous step-up mode for operating a converter 200 continuously and in an intermittent step-up mode for operating the converter 200 intermittently. While origin adjustment control for resolvers 25, 125 of motor-generators 110, 120 is performed, the control apparatus 500 does not control the converter 200 in the intermittent step-up mode. |
