Abstract

The present invention includes: a converter configured to convert the direct-current voltage of the rectifier to another direct-current voltage and supply to a load; a peak hold unit configured to hold a peak value of a current detected by a current detecting unit configured to detect a current flowing in the switching element; an averaging unit configured to convert, to a current, an output of an n/2 output unit, and then integrate and output the converted current, the n/2 output unit configured to output n/2 (n is an integer of 1 or more) of the held peak value only in a regeneration current period of the reactor; a control unit configured to turn the switching element on and off based on an output signal of the averaging unit in such a way that an average current value of a current flowing in the reactor is equal to a predetermined value.
