Time-Domain Homogenization of Windings Using B-Input Cauer Ladder Network Method

This article proposes a time-domain homogenization technique for windings using the B-input Cauer ladder network (CLN) method. First, the novel CLN procedure is presented to derive the equivalent circuit of a unit cell that acts as a homogenized model of the winding. The validity of the proposed method is then verified by comparing it with the results of homogenization of a winding using a semi-analytical approach. Finally, the derived equivalent circuit is applied to finite-element analysis (FEA) of a flat-wire inductor to demonstrate the effectiveness of the proposed method.
