Thanks for the tip Matter45
Here is the datasheet for the mosfet: http://www.google.no/url?sa=t&rct=j...e5Mi1MgWJ8R-2VGohynpDPg&bvm=bv.46340616,d.Yms
I assume you mean "the longer the mosfet is OFF..."?the longer the mosfet is on, the more potential difference it developes between source and drain
I use a high side gate driver so that should be covered.Point Two.
I have tried this but I couldn't get it to work because I then had two different ground potentials and therefore I was not able to sense the right voltage for the feedback loop. But I'd really appreciate it if you'd help me with it.Point three. having the N channel mosfet on the negative side of the circuit
