摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In a driving system, an applying module applies, in response to an input of an on or off command as a switching command, a switch signal to a target switching element as a high- or low-side switching element to switch the target switching element to be an on or off state. A measuring module measures a delay period defined as a time interval from a first time to a second time. The first time represents a time at which the switching command is switched from one of the on command and the off command to the other. The second time represents a time at which the target switching element is actually switched to be the on or off state. An adjusting module adjusts, based on the delay period, an input timing of a next switch signal applied from the applying module to the target switching element.

摘要： 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.
