Solved: IGBT turn-off voltage
Taking AIKW40N65DH5 as an example, the maximum recommended negative shutdown voltage for IGBT is -20V, but in practice, the range of -12 to -5V is chosen. Negative

Positive and Negative Voltage Control of IGBT, and the Turn-off
To turn on the IGBT, a positive voltage is applied between the gate and the emitter. However, this positive voltage must be higher than the threshold voltage. If the voltage between the gate and

TD351 Advanced IGBT Driver Principles of operation and
The fast turn-off of the IGBT generates a voltage spike on Vce reaching 1 kV, which is dangerously close to the IGBT absolute maximum rating (1200 V). The calculated turn-off

Modern high-voltage IGBTs and their turn-off performance
High voltage IGBTs have a limited turn-off capability. The use of large size or paralleled IGBTs leads to large inductive voltage drops in the commutation circuits. In this paper, a simple

Limits and Hints how to Turn Off IGBTs with Unipolar Supply
The small gap between the gate turn-off voltage and the threshold voltage of the IGBT increases the risk of parasitic turn-on of the IGBTs. Parasitic switching can be caused by the feedback

IGBT Characteristics
In an inductive turn-off the voltage swings from a few volts to the supply voltage with constant current and with no channel current (gate voltage has gone to zero).
