Abstract

An improved method for calculating the inductance of the air-gap inductor is introduced. The existing calculation methods mainly focus on the air-gap fringing effect while ignoring the winding reluctance's influence. In some large-capacity occasions, since the winding of the inductor also has a large volume, the influence of the winding reluctance on the inductance value cannot be ignored. In this paper, the winding reluctance is calculated, and the total inductance is solved based on a magnetic reluctance model. The results show that the proposed method is effective.
