How can I make a load inductor for a double pulse test?
How can I make a load inductor in the lab with value of roughly 115 uH for the sake of a double pulse test measurement? Do I need an LC meter to do that?

Bandwidth: voltage-source vs. current-source gate drivers
Why do voltage-source gate drivers provide low-to-medium bandwidth that does not work well for wide band gap devices, while current-source gate drivers provide hundreds of MHz of bandwidth?

What is the reason why thermal aging affects only the Cds capacitance but not the Cgs or Cgd capacitances?
Please take a look at the following images, experimentally obtained from a power cycling test of a power MOSFET. After the test where thermal aging is created due to repetitive power cycles, it is ...

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 (...
