Abstract:
Systems and methods for mitigating occurrences of dynamic avalanche events are presented. An electrical system may include a gate-drive unit electrically coupled to a semiconductor switching device and used to drive the switching device by applying a voltage to a gate terminal of the switching device. The electrical system may also include a controller that indicates the switching device to turn off and determines system parameters in response to the switching device turning-off. The controller may determine an intermediate gate voltage based at least in part on the system parameters and may modify the gate-drive unit configuration to apply the appropriate intermediate gate voltage to the gate terminal. The controller may additionally modify the gate-drive unit configuration to apply a turn-off voltage at the gate terminal subsequent to the application of the intermediate gate voltage.
