Snubber Circuit

[razor6271]

Hello,
So I have been working on this project (attached) and was struggling with ways to find the correct values for the snubber circuit (highlighted) to work in the most efficient ways. I wanted help regarding ways I can find value in the snubber circuit (Due to the MOSFET’s gate capacitance, the resistors and capacitor on the line between the op-amp and the MOSFET are needed to reduce the bandwidth of the circuit and prevent oscillations) by simulating the circuit in LTSpice.

Zip your ASC file from LTSpice and be sure to include all loads, cable capacitance and all other important parameters .

But it is better to specify all outputs, V,I (t) because your design may not be practical
