Fast and Robust Method for Mutual Inductance Calculation of Coaxial Circular Coils with Rectangular Cross Section

New and extremely fast and precise method for calculating mutual inductance between coaxial circular coils with rectangular cross section in air is presented. It is thoroughly compared with all recently published methods in the same computing environment and the results confirm the above stated. The emphasis in testing has been put on real power transformer conductor dimensions and analysing the accuracy and computational cost the applicability of the presented method is proven. Excellent numerical stability and agreement with professional software was found in all testing cases.
