Abstract :
The switching characteristics (turn-on and turn-off) and forward conduction drop of trench-gate IGBTs are examined over a temperature range of -150 to 150/spl deg/C. An analytical description of the forward conduction voltage drop is presented based on temperature dependencies of the appropriate physical parameters and mechanisms. A physics-based PSpice model, incorporating much of the device behavior, is also described. Results from the model are compared to experimental waveforms and discrepancies are discussed.
