Abstract
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 elementand 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 elementand the time of turning ON of the switching element j is brought back to the specified range.
