N2 - Among many works reported in the literature for mutual inductance (MI) calculation, Grover's filament method remains the most accepted standard for firsthandMI computation till today. Although Grover's method is fairly accurate, its implementation process becomes complicated due to the use of different formulae for various arrangements of filaments in a coil. The work presented in this paper describes a generalized semianalytic MI computation method applicable for coils of any geometries and misalignments. The method works by discretizing the area of the secondary coil in terms of triangular elements and the flux distribution on the secondary coil is calculated using Biot-Savart law. The MI of the coils is calculated for all considered geometries with vertical, lateral, planar and angular misalignments in space. Comparison of calculated MI values with experimental results are given.
