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.

Abstract: In a driver apparatus for driving a voltage-controlled switching element, an absolute value of a voltage difference between a voltage at a reference terminal that is one of terminals of a current path of the switching element and a voltage at the switching control terminal of the switching element is clamped at a clamping voltage greater than a threshold voltage. A voltage greater than the threshold voltage applied to the switching control terminal allows the switching element to be turned on. When the current flowing through the switching element becomes equal to or greater than a clamp threshold after the switching element transitions from an off-state to an on-state, a voltage-drop-rate at which the absolute value is decreased to the clamping voltage is decreased.

Abstract: A drive unit includes a charging unit which charges an opening/closing control terminal of a switching element to switch a drive state. The switching element includes a sensing terminal which outputs a minute current having a correlation with current flowing between input and output terminals of the switching element. The sensing terminal and either of the output terminal or a member having a potential equal to that of the output terminal are connected via a sensing resistor. The drive unit further includes an active gate control unit which changes a charge rate based on comparison of sensing voltage, which is a potential difference across the sensing resistor, or a rate of change of the sensing voltage with a specified value. The specified value is set based on individual-difference information of the switching element which indicates a characteristic, which affects the sensing voltage, when the drive state is switched.
