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.

Abstract: An insulated power supply apparatus includes an upper arm transformer which has a primary side coil and a secondary side coil, a lower arm transformer which has a primary side coil and a secondary side coil, and a power supply control section which has a voltage control switching element and an integrated circuit which turns on or off the voltage control switching element. At least one of the upper arm transformer and the lower arm transformer is adjacent to the power supply control section when viewing a surface of the substrate from a front thereof. An electric path transfers output voltage of the secondary side coil of the transformer adjacent to the power supply control section, to the integrated circuit. The integrated circuit turns on or off the voltage control switching element to perform feedback control so that the output voltage detected via the electric path reaches a target 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: 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.
