| Abstract |
This work proposes a new modeling approach for spiral inductive components which is based on the Partial Element Equivalent Circuit (PEEC) method extended to rotational symmetry case. In this context, analytic approximations of all integral formulas are proposed in order to reduce computing time for simulations of the partial inductance and capacitance coefficients with satisfying accuracy. Globally, this approach provides an efficient tool for inductive components design. A full modeling method providing the complex impedance frequency response is illustrated through examples on power applications. An illustration is also given on the ability of the model to show the charge and current densities distribution in conductors. The limits of the present model in terms of capacitive effects modeling are discussed and perspectives of evolution are focused on. |
