Abstract
A driving apparatus is provided, the driving apparatus including: a gate driving unit that drives a semiconductor element; a sampling unit that samples, in an on-period of the semiconductor element, an observation value that changes according to an on-current flowing through the semiconductor element; and a changing unit that changes a driving condition under which the gate driving unit drives a gate of the semiconductor element when the semiconductor element is turned off according to the observation value sampled in an on-period of the semiconductor element.
