“…In these systems, to have a high inductance and flat configuration, spiral windings are used [1][2][3]. Besides, these coils have an extensive application in power electronics and dc/dc converters due to their flatness and special configuration; so they are better replacement for the ordinary inductances to reduce the volume of the converter [4][5][6][7].…”

Abstract-Due to the special structure of current carrying planar spiral coils, precise calculation of the forces between them is complicated and time-consuming. To overcome these problems, in this paper a new and fast method is proposed for calculation of the magnetic forces between planar spiral coils. The advantage of the proposed method is that just by having the external dimension of coils and their number of turns, the force between them at different distances and with different currents can be calculated. The results obtained by direct and proposed calculation methods show the efficiency of the latter in simplicity and calculation time. The precision of the proposed method has been confirmed by experimental tests done on constructed coils.

“…In these systems, to have a high inductance and flat configuration, spiral windings are employed [1][2][3]. Besides, these coils have an extensive application in power electronics and DC/DC converters due to their flatness and special configuration; so, they are better replacement for the ordinary inductances in order to reduce the volume of the converter [4][5][6][7] In recent decades, spiral coils are employed in casting industries to form the thin metal sheets. In [8] the finite difference method is employed to calculate the force between them; furthermore, in this reference to calculate the magnetic force, spiral coils are replaced by concentric rings, but there is no study and discussion on the precision of the method.…”
