In a DC/DC converter, each channel operates under digital control using nonlinear control. The time interval between the time of turning ON of the switching element 1 and the time of turning ON of each of other switching elements j (j=2, 3, . . . , N) is measured. If the measured interval is within a specified range, operation is continued without changing the ON time of the switching element j used last time. Meanwhile, if the measured interval is out of the range, the ON time of the switching element j is increased or decreased within a predetermined range to be shifted from a basic frequency. Thus, the interval between the time of turning ON of the switching element 1 and the time of turning ON of the switching element j is brought back to the specified range. |
