POWER SUPPLY DEVICE OF VEHICLE

摘要

A control device (500) controls a boost converter (200) to be operated in one of a continuous voltage-boosting mode in which the converter (200) is continuously operated and in an intermittent voltage-boosting mode in which the converter (200) is intermittently operated. The control device (500) permits the converter (200) to be controlled in the intermittent voltage-boosting mode when an atmospheric pressure is equal to or greater than a first prescribed value, and inhibits the converter (200) from being controlled in the intermittent voltage-boosting mode when the atmospheric pressure is less than the first prescribed value.
