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 7):
The gate drive controller of  claim 1 , further comprising:\n a timer configured to be set to count-down value by the MCU, the timer providing a signal to the MCU when the count-down value has counted down to zero; wherein: the program instructions that cause the MCU to generate the first drive signal and the first target value further cause the MCU to provide a first count-down value to the timer; 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 the earlier occurring of the timer value counting the first count-down value to zero or the Boolean signal exhibiting the first transition between the first value and the second value; the program instructions that cause the MCU to provide the second drive signal and the second target value further cause the MCU to provide a second count-down value to the timer; 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 the earlier occurring of the timer value counting the second count-down value to zero or the Boolean signal exhibiting the second transition between the first value and the second value.
