Description
Summary:The layout and wounded components are sources of radiated perturbations in static converters. Used to reduce conducted perturbations, common mode filters can be responsible of the incompliance to radiated standards. Magnetic field computation of common mode filters allows defining their radiated perturbation level during the definition. This allows earning time considering the design process of the whole system (static converter-filter-driver) is an important gain of time. An original modeling method is presented. The common mode inductance is modeled using finite element method. The layout is modeled using partial element equivalent circuit (PEEC) method. Then, the PEEC model is imported into the finite element one. By this way, interaction phenomena between the inductance and the layout are modeled.
