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 31):
The gate drive controller of  claim 24 , including a further comparator, having a further reference input terminal, a further signal input terminal, coupled to receive the output signal of the power semiconductor device, and a further output terminal, the further comparator providing a further Boolean output signal that is in a first state when a value of a signal applied to the further signal input terminal is less than a reference value applied to the further reference input terminal and in a second state when the value of the signal applied to the further signal input terminal is greater than or equal to the reference value applied to the further reference input terminal; and\n the program instructions cause the MCU to apply the first reference value to the comparator and the second reference value to the further comparator and to generate the fourth drive signal when the further Boolean signal changes between the second state and the first state.
