According to the present invention, a bidirectional buck boost DC-DC converter can be obtained, in which power can flow bidirectionally from a primary side to a secondary side and from the secondary side to the primary side, regardless of a magnitude relation between a secondary-side voltage and a primary-side voltage in a state where different DC voltage sources are connected to the primary side and the secondary side in the DC-DC converter. A direction and a magnitude of the power can be automatically controlled to a desired value continuously on instantaneous value basis.
