Abstract
Until an output voltage of a converter reaches a threshold value, a control part performs switching control, and after the output voltage reaches the threshold value, the control part performs supply voltage control while the state of a switching control signal at the time when the output voltage reaches the threshold value is maintained. Switching control is a control method in which the output voltage is adjusted by adjusting the frequency or duty ratio of the switching control signal that drives a driving part. Supply voltage control is a control method in which the output voltage is adjusted by adjusting the supply voltage that is applied to the primary side of the converter.
