One-dimensional non stationary analytical models are presented describing the turn-off behaviour of the non-punch-through IGBT (NPT-IGBT) driven in a chopper circuit with a clamped inductive load. For this purpose the ambipolar device equations are solved by the integral method. Analytical ...

Turn-off failure of IGBTs under clamped inductive load This paper reports the mechanism of failure of IGBTs during clamped inductive switching stress. With the help of measurements and two-dimensional (2-D) numerical simulations, the turn-off failure of IGBTs under clamped inductive load is .....
Turn off behaviour of power MOSFETS with quasi-clamped inductive switching (QIS) loads is analysed. In most real applications the main inductive load is clamped during turn off but there is enough unclamped inductance in the circuit to cause voltage spikes and avalanche breakdown. This is the QIS...
for short-circuit failure. The clamped inductive load (CIL) turn-off test is very commonly used as a benchmark circuit by several IGBT manufacturers [7]–[9]. It tests the ability of a device to repetitively turn off the specified current with a CIL. ...
