The series R-L equivalent circuit model, often used to represent laminated busbar impedance in time-domain simulations, cannot provide accurate results because the effective AC laminated busbar resistance and inductance depend on frequency. Using the series R-L model yields incorrect predictions of damping and losses that occur at high frequencies. This paper shows that a Cauer network model, developed for microwave applications, can be adapted to accurately model laminated busbar impedance over a wide frequency range. This paper presents the procedure for determining the appropriate time-domain circuit element values using only the laminated busbar dimensions
