Abstract
A power supply apparatus for a vehicle includes first and second batteries, a power supply line, first and second boost converters, a system main relay, a capacitor, and a control device controlling the first and second boost converters and a connecting portion. Upon receiving a startup instruction IGON, the control device controls the first boost converter such that a feeding node capacitor is charged from the first battery, and controls the second boost converter such that the capacitor is charged from the power supply line. After the charging of the capacitor is completed, the control device switches the system main relay from a disconnected state to a connected state.
