Abstract: In a driver, a charging module stores negative charge on the gate of a switching element via a normal electrical path to charge the switching element upon a drive signal representing change of an on state to an off state. This shifts the on state of the switching element to the off state. An adjusting module changes a value of a parameter correlating with a charging rate of the switching element through the normal electrical path as a function of an input signal to the driver. The input signal represents a current flowing through the conductive path, a voltage across both ends of the conductive path, or a voltage at the gate. A disabling module disables the adjusting module from changing the value of the parameter if the drive signal represents the on state of the switching element.

Abstract: In an integrated circuit formed into a single chip, a drive signal generating unit generates drive signals for switching elements of a power conversion circuit. A monitoring unit monitors a microcomputer that calculates generation information that is information used to generate the drive signals, and determines whether or not an abnormality has occurred in the microcomputer. An angle converting unit converts an output signal of an angle sensor to rotation angle information of a rotating electric machine. A drive signal generating unit generates the drive signals for controlling driving of the rotating electric machine based on the generation information and the rotation angle information when the monitoring unit determines that an abnormality has not occurred in the microcomputer, and generates the drive signals based on the rotation angle information, without using the generation information, when the monitoring unit determines that an abnormality has occurred in the microcomputer.

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 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: In a switching control circuit, a determiner determines whether there is one of a first type of abnormality and a second type of abnormality different therefrom in a target switching element and/or the switching control circuit. A controller controls a second switching element to close a low-impedance discharge path for discharging a control terminal of the target switching element when it is determined that there is the first type of abnormality, and disables closing of a high-impedance discharge path for discharging the control terminal while the low-impedance discharge path is closed by the second switching element. The controller controls a third switching element to close the high-impedance discharge path when it is determined that there is the second type of abnormality; and disables closing of the low-impedance discharge path while the high-impedance discharge path is closed by the third switching element.

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.
