I'm planning on using a dual inductor in series mode to increase the inductance.
I realize that the total inductance will be L1+L2+2M where M is the mutual inductance (when the polarity is connected to give aiding, rather than opposing, magnetic flux).
My question, though, is whether the saturation current will decrease by using this arrangement. My initial thought is that it won't change (appreciably) since, although the flux is doubled, the effective core length used is also doubled. Is my thinking correct?
