What does the cross point of V-I curves mean?
Here you see a V-I graph including many curves achieved under different junction temperatures of an IGBT. As it can be seen there is a cross point where all curves intersect each other. Does it make ...

Zero Voltage in a power semiconductor chip
In an ON-mode silicon IGBT chip operating within a real power module, is the collector contact fixed at 0 V or emitter?
What about Power SiC MOSFET?

Ic and Vce equations of IGBT
I know in IGBTs while operating, parameters Ic (collector current) and Vce (collector-emitter voltage) are Tj (junction temperature) and Vge (gate-emitter voltage) dependent. Is there anything else ...

Calculation of Vce from Ic-Vge Characteristic
We have found the Ic-Vge (collector current vs gate-emitter voltage) characteristic of an IGBT device as shown below at a high Vce (collector-emitter voltage) value (here 20V) from the datasheet (...

on-state voltage
I am trying to study an ever-on IGBT. in other words, IGBT is tried to be on in a long time. To this purpose, a +15V constant dc voltage is applied to the gate-emitter. But, when connecting a +2V ...
