A DC-DC converter of the present invention, located between an end at a low potential and an end at a high potential with different DC potentials, for transmitting DC power from the end at the low potential to the end at the high potential or from the end at the high potential to the end at the low potential, comprising: a buck-boost circuit equipped with a buck switch and a boost switch connected in series at the end at the high potential; and a controller for adjusting periods of turning on the buck switch and the boost switch depending on transmission direction and transmission rate of DC power for a requirement; wherein, if the DC power is transmitted from the end at the low potential to the end at the high potential, the controller may turn on the boost switch for a first section and turn on the buck switch for a second section shorter than the first section during the turn-off period of the boost switch.
