I've seen it said that bifilar winding 'multiplies' the inductive field. But that doesn't seem to make sense to me, since parallel inductors reduce total inductance.
Let's say for a particular core I need 20 windings of a single wire to get X microfarads. How many windings of each wire would be needed for a bifilar on that same core to get X microfards?
Thank you lots, my litz choices are limited so I need to do bifilar to meet my ampacity needs.
