PROBLEM TO BE SOLVED: To minimize the influence of a ripple current. SOLUTION: The DC-DC converter 10 comprises an input node 14 for receiving a DC supply power from a fuel cell 12, an output node 16 for providing a DC output power, and an inductor 17 having an inductance nonlinearly changing with respect to an inductor current. A first terminal 30 of the inductor 17 is coupled to the node 14 for receiving the DC supplied power from the cell 12. A switch 20 is connected between the second terminal 32 of the inductor 17 and a ground. A control circuit 22 switches a switch 20 between an open position and a closed position. |
