EE 2415 Stored Energy in Magnetically Coupled Inductors
General Integration Path • Conservative magnetic field • Energy independent of path of integration
Equivalence • In a conservative field, Lkm = Lmk • In general:
Aiding and Opposing Flux • When both currents enter the polarity marks or when both currents exit from the polarity marks, the mutual inductance, Lkm is considered as positive. • Otherwise, Lkm is negative.
Aiding and Opposing Flux • Here, L12 = L21 would be considered negative.
