Abstract
Provided is a switching control method for an isolated bidirectional DC-DC converter, wherein the isolated bidirectional DC-DC converter connected between a DC grid system and a battery uses multiple switching controls together depending on a voltage of the battery, thereby facilitating high efficiency control. In the isolated bidirectional DC-DC converter according to the present invention, switching of a first switching unit and a second switching unit is controlled to control the flow of power by changing the bidirectional DC-DC voltage between the DC grid system and the battery, and the first and the second switching unit are switched using PSM switching control, SPWM switching control, and DPWM switching control together depending on a voltage with which the battery is charged and load capacity, thereby enhancing efficiency of the system.
