摘要： A power supply device has a pulse width control circuit for controlling voltage converting operation of a voltage converting circuit by changing a pulse width. A momentary interruption detecting circuit detects a change in an output voltage when the output voltage suffers a momentary interruption over a short period of time. A full short-circuit detecting circuit detects a change in the output voltage when the output voltage suffers a short circuit over a very short period of time. A short-circuit control circuit stops a pulse width changing control process of the pulse width control circuit a predetermined period of time after the momentary interruption detecting circuit has detected that the output voltage suffers a momentary interruption, and stops the pulse width changing control process of the pulse width control circuit immediately when the full short-circuit detecting circuit detects that the output voltage suffers a short circuit.
