    Hi everyone, I'm new here.

    I'm doing my master's thesis about failure detection in DC-DC converters and at the moment I'm going through some simulations. The problem is that real inductors have a current dependent inductance and this is not modeled in the inductor model I have in LTspice. Usually the inductance decreases with increasing DC current and I'd like to know if I can find a spice model for this kind of inductor.

    So if anyone can help with this, it would be highly appreciated.
