Abstract
In an apparatus, a predicting unit predicts, based on a target value of a drive mode of a power converter at a next timing, a first value of a controlled variable. The drive mode is indicative of a switching-state of each of a plurality of switching elements. The target value of the drive mode of the power converter at the next timing is temporarily set at a present timing prior to the next timing. A driving unit drives the plurality of switching elements based on the target value of the drive mode at the next timing while limiting a number of switching-state changes in the plurality of switching elements from the present timing to the next timing as long as the deviation between the predicted first value of the controlled variable at the further next timing and a command value therefor is within a threshold range.
