Abstract
A DC-DC converter includes a bridge circuit electrically connected to a DC link capacitor; an inductor and a capacitor electrically connected to the bridge circuit, in which the inductor is connected to a first end of a battery, and the capacitor is connected to the first end and a second end of the battery; a sensor configured to sense a voltage between the bridge circuit and the DC link capacitor; and a controller configured to control switching operations of the bridge circuit so that a power output by the DC-DC converter and supplied to the first end of the battery has a droop curve-shaped power value according to the sensed voltage.
