Abstract
A power supply apparatus () according to the present disclosure converts an input voltage supplied from a power source to a predetermined direct current voltage. The power supply apparatus () includes an inrush current prevention circuit () based on a buck converter system and configured to suppress a flow of inrush current from the power source to the power supply apparatus () and a boost converter circuit () configured to output the predetermined direct current voltage. A choke coil () included in the inrush current prevention circuit () and a choke coil () included in the boost converter circuit () are a common choke coil. A smoothing capacitor () included in the inrush current prevention circuit () and a smoothing capacitor () included in the boost converter circuit () are a common smoothing capacitor.
