| Abstract |
The paper shows, that the miller capacitance of IGBTs has not only the well known voltage dependency, but dependents also on the collector current and the gate drive conditions. The differential miller capacitance might even become negative, which leads to a self-turn-off process of the IGBT during switching transients. Measurement and simulation results are presented which show this self-turn-off. |
