چکیده :

The air core inductor has diverse types, one of which is the multilayer planar spiral air-core inductor (MPSACI). In spite of many potential applications for such an inductor in power electronic circuits and systems, a limited number of research works can be found in the technical literature dealing with the precise design of the MPSACI. Hence, a method for accurate designing of an MPSACI has been presented in this paper. In the proposed method, self and mutual inductances are precisely calculated, and the total inductance is obtained based on these two inductances. First, an analytical calculation of the MPSACI is presented, and then the associated results are validated by the 3D finite element method (FEM) and experimental inductance measurements on a prototype MPSACI. Finally, other design parameters are investigated to present all aspects of a comprehensive design of the MPSACI.
