First Claim
1. A device, comprising:
- a controller configured to regulate one or more voltages applied to a gate of an insulated gate bipolar transistor (IGBT) configured to;
generate a gating signal and transmit the gating signal to the IGBT,wherein the gating signal is configured to activate or deactivate the IGBT; and
generate a voltage clamping signal and transmit the voltage clamping signal to activate or deactivate a transistor, wherein a terminal of the transistor is directly coupled to a gate of the IGBT, and wherein the transistor is configured to periodically limit a peak operational voltage value of the IGBT based at least in part on one or more characteristics of the voltage clamping signal, and wherein the peak operational voltage value is greater than a voltage of the gating signal.

Abstract
A device includes a controller configured to regulate one or more voltages applied to a gate of an insulated gate bipolar transistor (IGBT). The controller is configured to receive one or more voltage values associated with the IGBT, and generate a gating signal and transmit the gating signal to the IGBT. The gating signal is configured to activate or deactivate the IGBT. The controller is configured to generate a voltage clamping signal and transmit the voltage clamping signal to activate or deactivate an active switching device. The active switching device is configured to periodically limit the one or more voltage values associated with the IGBT based at least in part on one or more characteristics of the voltage clamping signal.
