摘要： A control apparatus of a DC-DC converter includes a reactor and a switching element, repeats an accumulation and a discharge of energy of the reactor by a switching operation of the switching element, and converts a direct-current input voltage to acquire a direct-current output voltage. The control apparatus includes: a current value acquiring unit that acquires current values of the reactor in a current rising section and a current descending section of a current waveform of the reactor at a time interval of a half of a switching period of the switching element; and a center value estimating unit that estimates a center value of a current of the reactor based on the current values acquired in the current rising section and the current descending section.
