Guys,
I'm a little bit confused about all the above terms. They seem to be used interchangably in some text.
Are all these term the same?
Also, there seem to be 2 formulas for these term.
With coupling coefficient = k.
1). Lm = KxLp., Lr = (1-k)xLp
And
2) M = k*sqrt(Lpri*Lsec).
There's also a formula with Leakage inductance = (1-k)*(1-k)*Lp
My understanding is, you use 1) if you have ideal transformer in the equivalent circuit and use 2) for a T-Equivalent circuit.
Is this correct understand?
TIA,
KJ
