Abstract: In a driving system for driving a switching element, a controller controls the switching element. A temperature measuring module measures a temperature of the switching element, and output a first signal representing the measured temperature of the switching element as first information. A state determining module determines whether the switching element is in a specified temperature state based on the first signal, and outputs a second signal representing a result of the determination as second information. A communication medium communicably connects between the controller and the state determining module, and the second signal output from the state determining module being transferred to the controller via the communication medium. The controller determines how to drive the switching element based on the second information in the second signal transferred thereto via the communication medium.

Abstract: In a driver, a dissipating unit dissipates, upon a potential difference between input and output terminals of a switching element being lower than a predetermined potential, electrical charge for overcurrent detection between the input and output terminals. The dissipating unit includes a rectifier having a pair of first and second conductive terminals. The first conductive terminal is connected to the input terminal of the switching element. An overcurrent determiner determines that an overcurrent flows between the input and output terminals of the switching element upon determination that electrical charge has not been dissipated by the dissipating unit despite the change of the switching element from the off state to the on state. A failure determiner determines whether there is a failure in the dissipating unit as a function of a potential at a point on the first electrical path from the failure determiner to the second conductive terminal.

Abstract: In a driver, a changing module changes a rate of discharging the control terminal of a switch at least between a first value and a second value lower than the first value. A measuring module measures a value of a parameter as a function of a current flowing through the conductive path of the switch during a drive signal being in an on state. A control module controls the changing module, as a function of the value of the parameter, to select the first value or the second value as the rate of discharging the control terminal of the switch upon the drive signal directing a change from the on state of the switch to an off state thereof. The control module discharges the control terminal of the switch using the selected value as the rate of discharging the control terminal of the switch.

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.
