Abstract
A control device controls a switching element that is connected to a conductor and that executes a switching operation for causing the conductor to switch between conductive and non-conductive states. The control device includes an element controller and a current value measurer. When a target conduction ratio is a positive value lower than 1, the element controller controls the switching element to be in an on-state during a period defined by a switching cycle and a detective conduction ratio than the target conduction ratio and equal to or lower than 1, in at least one cycle that is each the switching cycle. The current value measurer measures a value of direct current flowing in the conductor, based on a detected current value that is digital data generated in every sampling cycle independent from the switching cycle by detection of a current sensor signal output from a current sensor.
