Abstract

See full text

Provided is a power supply device configured to diagnose circuit operation, and identify, if a defect is found in the diagnosis, the circuit component that is the cause. The power supply device includes: a switch that is disposed in a power supply path leading from a main power source to a load, and is configured to bring into conduction and interrupt the power supply path; a downstream sensing means for sensing a power supply state of a load-side power supply path between the switch and the load; a comparing means for comparing a downstream voltage of the load-side power supply path, with a predetermined threshold voltage; and a control unit. The control unit includes: a switch control means for turning the switch on/off; and a conduction determination means for determining whether the switch is in an ON or OFF state based on the output of the downstream sensing means.
