Abstract
In a driver, a charging module electrically charges the on-off control terminal of the switching element for turning on the switching element, and a limiting module performs a task of limiting a voltage at the on-off control terminal of the switching element by a predetermined voltage to thereby limit an increase of a current flowing between the input and output terminals of the switching element. A determining module determines whether the voltage at the on-off control terminal of the switching element deviates from the predetermined voltage while the limiting module is performing the limiting task. A correcting module corrects the voltage at the on-off control terminal of the switching element to be close to the predetermined voltage when it is determined that the voltage at the on-off control terminal of the switching element deviates from the predetermined voltage.
