Hello,
Do you agree that in the attached schematic, the current sense transformer primary is not in the optimal place. Rather, it should be upstream of the FET….as it stands, it is in the switching node, which due to its rapid dv/dt, will make the signal from its secondary more noisy.
Do you agree?

These rhetorical questions are really boring.

Why did you place the current sense there if you think it's wrong?
