This video is intended to clarify the modelling of couple inductors and transformers. It is demonstrated how both models are equivalent even though they have a different number of parameters. The coupled inductor model has only three parameters: two self inductances and the coupling factor, while the transformer model has four: one magnetizing inductance, two leakage inductances (primary and secondary) and the ideal transformer turns ratio. Only three parameters of the transformer model are independent, the fourth one can be arbitrarily selected. Find out more by watching the video ...

Estimado profesor Marcos Alonso, Quiero agradecerte por el excelente video sobre la modelización de inductores acoplados y transformadores. Fue muy claro y bien didáctico, lo que hizo que el tema fuera fácil de entender. Tu habilidad para simplificar conceptos complejos es digna de destacar. Un gran saludo desde argentina!

Muchas gracias por este video tan bien explicado. Estaba buscando la explicación de la relación entre el modelo de bobinas acopladas y el modelo transformador que se utiliza normalmente y este video es estupendo. Ya sólo me queda entender como se pueden modelar las pérdidas del núcleo en el modelo de bobinas acopladas y la relación entre los dos modelos cuando hay pérdidas. Los libros de teoría de circuitos (como Sadiku) usan el modelo de bobinas acopladas para explicar transformadores y los de máquinas eléctricas plantean el modelo del transformador sin más, sin explicar la relación entre estos dos...

What should we do if we get a negative inductance value? In this case, T-model simulation is impossible?

Mathematically it should be OK to use negative inductances but LTspice does not like them. It won't converge. In this case it is better to use the other models. See video PE #32 for more info: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kNdv27OO2o0.html

Great video , thanks a lot professor , it would be nice to address the modelling of a multiport transformer , specially the ones used in SMPS, like flyback

Dear Marcos, Thanks for the great explanation with a simulation. Could you also do a similar video for multi winding transformer modelling? (Coupled inductor model and transformer model for multi winding).. Thank you..

Thank you very much for your comment. I agree. This is an interesting topic for a future video.

Marcos, great video, muchas gracias. I have an issue where the analysis of coupled inductors using loop equations and using the t-model does not provide the same answer. The analysis is done at resonance, and I"m wondering if the model equivalency breaks down under some conditions. Per the measured Vp and Isecondary measured, the T-model circuit provides seemingly the correct behavior. Both solutions agree when the primary and secondary are symmetric (ie, Rp = Rs, Lp=Ls, s and Rs are the same. However, when Lp and Ls (and Rs and Rp) are different, the T-model adds real term to the mutual impedance that the coupled inductor model does not. Do you have any experience or insight regarding this?

Hello, Jorge, thanks for your comment. Both models are equivalent. There must be something else. I would need more information to look into it.

@@MarcosAlonsoElectronics gracias por responder. Encontré el error en el analysis del T-model....todo cuadra como es debido. Feliz Navidad! Saludos.
