So I am trying to simulate a wireless power transfer via coupled coils. I am using the cantilever model (source: http://denverpels.org/Downloads/Denver_PELS_20070410_Hesterman_Magnetic_Coupling.pdf).
I am just having doubts about the current. From what I understand, the two inductances, L1 and L2 in the cantilever model are the leakage and magnetizing inductances which aren't physical inductances. In the figure I uploaded, I am simulating two coils that have: k = 0.3 (coupling) L1 = L2 = 7.64 uH (self-inductances)
Now, I just wanted to know, what is the actual current that goes through the transmitter coil (primary winding in this case)? Is it the current going through the red junction or blue junction?
In other words, what is the simulated current that I should use in order to properly choose the wire gauge if I wanted to coil (based on current)?
I believe that it should be the current going through the red junction since the said figure is the equivalent model of the coupled coil with some mutual inductance M, but I just wanted to make sure.
