Hello,

Can somebody describe me how to calculate mutual inductance and coupling coefficient for center tap transformer (secondary side center tapped)? Do I need to analyze secondary side windings separately or together? I found nice pdf (attached) for normal transformer but cannot google anything for center tap. Would be much appreciated for simple straightforward explanation similar to this one from pdf for normal transformer.

I'm no expert but, can't see how there is a difference in a "normal transformer"(your words) and a "center tap transformer". They are a "normal" form of transformer. The center tap is just a way of getting two voltages from one transformer if needed. The center tap is just that, a tap/wire coming out of the secondary in the center. It is still only one coil,but they are made to make a transformer more versatile, like for a positive and negative(after rectifying) DC power supply.
