The power supply device includes a transformer, a switching unit for driving a primary side of the transformer, a control unit for outputting a pulse signal to the switching unit to control a switching operation including a period during which the switching unit is active and a period during which the switching unit is inactive, in order to output predetermined electric power from a secondary side of the transformer, and an output control unit for continuously outputting a pulse signal to the control unit in the period during which the switching unit is active, at a predetermined cycle shorter than the period during which the switching unit is inactive. |
