Abstract:
An IGBT die structure includes an auxiliary P well region. A terminal, that is not connected to any other IGBT terminal, is coupled to the auxiliary P well region. To accelerate IGBT turn on, a current is injected into the terminal during the turn on time. The injected current causes charge carriers to be injected into the N drift layer of the IGBT, thereby reducing turn on time. To accelerate IGBT turn off, charge carriers are removed from the N drift layer by drawing current out of the terminal. To reduce V CE(SAT) , current can also be injected into the terminal during IGBT on time. An IGBT assembly involves the IGBT die structure and an associated current injection/extraction circuit. As appropriate, the circuit injects or extracts current from the terminal depending on whether the IGBT is in a turn on time or is in a turn off time.

Claim (Index 29):
The method of  claim 28 , wherein emitter current flowing out of an emitter pad of the IGBT die structure causes energy to be stored in the current transformer of the IGBT assembly, and wherein the current transformer causes auxiliary current to flow back into an auxiliary pad of the IGBT die structure.
