A critique of the turn-on physics of power bipolar devices
This paper compares the turn-on performance of a vertical p-i-n diode and IGBT, under zero-voltage switching (ZVS). Although both the devices are "conductivity modulated" during turn-on, the IGBT carrier dynamics distinctly differ from that of a p-i-n diode. It is shown that, for identical drift region parameters, the conductivity modulation in IGBT is significantly lower compared to that in a p-i-n rectifier mainly because of carrier flow constraints in the IGBT and its inherent bipolar transistor-like nature. Two-dimensional (2D) mixed device and circuit simulations are performed to understand the behavior of the two devices during turn-on under ZVS.
