Abstract
An in-vehicle power supply apparatus includes a converter that outputs DC power. A first power storage device and a second power storage device are charged via the converter. A first switch selects on/off between the converter and the first power storage device. A second switch selects on/off between the converter and the second power storage device. A voltage monitoring circuit detects a DC voltage on the output side of the converter, at a point closer to the converter than are the first switch and the second switch.
