PROBLEM TO BE SOLVED: To provide DC-DC conversion equipment which can suppress bias magnetism that arises in a transformer though it is of simple constitution. SOLUTION: The DC-DC converter has a transformer, which transforms AC outputted from an inverter for converting DC into AC, a voltage detector, which detects the output voltage value of DC outputted from a converter for converting AC outputted from this transformer into DC, a voltage command which gives a command of voltage outputted from the converter, and an ON-OFF controller which regulates the output voltage of the inverter, receiving a differential value outputted from an error amplifier that gets a differential value between the output voltage value of the converter that the voltage detector has detected and the voltage command given from the voltage command. It is equipped with a band-reject filter which removes the signal of frequency components equal to the frequency of AC outputted from the inverter, being interposed in a path which reaches the ON-OFF controller from the voltage detector.
