Turning off a MOSFET
What is the advantage of turning off a MOSFET on negative gate to source biased voltage of 5V instead of 0V? … I saw that it is a very common phenomenon in SiC MOSFET as their datasheet always specifies a negative gate to source biased voltage to turn it off while in traditional silicon MOSFETs 0V is taken as turn …

Why do we need a small external gate to source capacitor for a MOSFET drive circuit?
I have a question regarding a MOSFET half bridge driver circuit. We always connect a small capcitor between the gate and source of both the high side and the low side switch, typically in picofarads. … The answer I have found is to reduce or compensate the effect of internal gate to source Cgs of MOSFET in order to achieve optimum switching performance. …

Difference in simulated and measured Eon, Eoff and Erevreq for double pulse test conducted o...
I conducted a double pulse test (DPT) on an AUIRFP4568 MOSFET in the lab as well as in LTspice. … With the same setup as used in the lab I created a setup in LTspice using the SPICE model of the MOSFET. The behaviour I am getting in terms of switching energies is completely different. …

What is wrong with my double pulse test setup in LTspice?
I am trying to make double pulse test measurements in LTspice using the spice model of a MOSFET and gate driver we are using in our actual design. … My setup seems to be not working as nothing is appearing on the gate of the low side MOSFET which is the device under test.
I have used the same components which we have used in our actual design. …
