PROBLEM TO BE SOLVED: To provide a DC/DC converter capable of using a compact reactor without generating current splitting variation at switching elements connected in parallel and without increasing a switching frequency.SOLUTION: The DC/DC converter is constituted of three semiconductor elements 411, 421, 431 mutually connected in parallel. On/off control of three switching elements 411s, 421s, 431s are made to be performed by mutually shifting phases by 1/3 of a switching frequency of the switching elements=120° so that a frequency of a voltage applied to the reactor 5 is three times that of a switching frequency of the switching elements. |
