AC resistance in inductor, using Maxwell

    • Patrick


      I'm trying to use Maxwell Transient Solver to calculate the AC resistance of the conductive element in an inductor.   The principle I'm attempting to use is that Rac = (Vapplied-Vinduced)/Total current.

      I am correctly viewing the skin effect portrayed in the J field so all good so far.

      But if I take Vapplied, Vinduced and the reported winding current,  the voltage delta divided by the reported total winding current yields a constant  resistance versus frequency.    I know the tool has better data than this, given it's correct representation of the J field.

      ( I also tried getting the total current from the field calculator, but again, I came out with a constant, which is incorrect.  )
