A switching circuit for use in a power converter is provided. The switching circuit includes an insulated gate bipolar transistor (IGBT) including a gate terminal, a collector terminal, and an emitter terminal, a gate drive circuit electrically coupled to the gate terminal and configured to switch the IGBT on and off, and, a temperature drift resistant clamp circuit electrically coupled between the gate terminal and the collector terminal of the IGBT, the temperature drift resistant clamp circuit configured to maintain a voltage at the collector terminal below a threshold voltage and facilitate reducing the effects of temperature on operation of the switching circuit. |
