Abstract:
In a drive unit for a switching element, a drive circuit changes the switching element between an on-state and an off-state, by controlling a potential difference between a reference terminal, which is one of a pair of ends of a current path of the switching element, and an opening-closing control terminal of the switching element. A determination section determines, if an on-operation command or an off-operation command is inputted as an operation signal for the switching element, whether or not the potential difference has reached a specific value toward which the potential difference shifts, in response to one of the operation commands, with respect to a threshold value by which the switching element is turned on. A forcible processing section removes charge for turning on the switching element from the opening-closing control terminal, if the determination section determines that the potential difference has not reached the specific value.
