Patent abstract
Systems, circuits, and methods for operating an Insulated-Gate Bipolar Transistor (IGBT) are provided. A circuit is to include a first driver for the IGBT, the first driver having a first resistance and being connectable to the gate of the IGBT. The circuit is further described to include a second driver for the IGBT, the second driver having a second resistance different from the first resistance and also being connectable to the gate of the IGBT. The circuit is also described to include a controller that receives at least two inputs regarding operating characteristics of the IGBT and based on the at least two inputs decides whether to connect the first or second driver to the gate of the IGBT during power-down of the IGBT.
