7. Conclusion

In order to carry out reliable simulations in power electronics, equivalent circuits capable of representing wound components are required. While that of a simple transformer is widely known, when the number of windings exceeds 3, few general representations are available.

In this dossier, we have presented a method for finding equivalent circuits capable of representing the magnetic coupling of any n-winding transformer. The study of magnetic coupling always provides the backbone of the circuits developed.

This method offers several advantages. Firstly, it uses a minimum number of components, equal to that of the independent elements of its inductance matrix. Secondly, the approach presented here is recursive, and equivalent diagrams are easily constructed as the number of windings increases. We have presented general equivalent circuits...
