Abstract: A DC/DC converter includes n converters connected in parallel to each other and configured to adjust a level of an input voltage according to a duty ratio of a first pulse signal applied to a first switch device to output an output voltage, wherein the n is an integer of 2 or more; and a control unit configured to compare an average of n sensing currents with the n sensing currents sensed from the converters, respectively, to adjust the duty ratio of the first pulse signal.
