Abstract:
A gate-drive controller for a power semiconductor device includes a master control unit (MCU) and one or more comparators that compare the output signal of the power semiconductor device to a reference value generated by the MCU. The MCU, in response to a turn-off trigger signal, generates a first intermediate drive signal for the power semiconductor device and generates a second intermediate drive signal, different from the first drive signal, when a DSAT signal indicates that the power semiconductor device is experiencing de-saturation. The MCU generates a final drive signal for the power semiconductor when the output signal of the one or more comparators indicates that the output signal of the power semiconductor device has changed relative to the reference value. The controller may also include a timer that causes the drive signals to change in predetermined intervals when the one or more comparators do not indicate a change.

Claim (Index 10):
The gate drive controller of  claim 8 , further comprising:\n a further comparator, the further comparator being coupled to receive a first further target value from the MCU, the first further target value representing a first further expected value of the output signal of the power semiconductor device after a power fluctuation in the output signal of the power semiconductor device has subsided, the power fluctuation resulting from the drive signal being changed, and to provide a further Boolean output signal having a first value when the output signal of the power semiconductor device is less than the further expected value and having a second value when the output signal the power semiconductor is greater than or equal to the further expected value; wherein:\n the program instructions that cause the MCU to hold the first drive signal until the Boolean signal exhibits the first transition between the first value and the second value further cause the MCU to hold the first drive signal until both the Boolean signal and the further Boolean signal exhibit respective first transitions between the first value and the second value; \n the program instructions that cause the MCU to provide a second drive signal, different from the first drive signal, and a second target value to the comparator in response to the first transition of the Boolean signal between the first and second values further cause the MCU to provide a second further target signal to the further comparator; and \n the program instructions that cause the MCU to hold the second drive signal until the Boolean signal exhibits the second transition between the first value and the second value further cause the MCU to hold the second drive signal until both the Boolean signal and the further Boolean signal exhibit respective second transitions between the first value and the second value.
