Abstract

The performance of the EMI filters on power-electronics applications is limited by the parasitic coupling between the components of the filters. While this coupling can be partially taken into account on the circuit level by including mutual inductance and capacitance elements to the filter circuit, it is difficult to estimate the values of these elements. In this work, a full-wave modeling strategy is proposed to estimate the parasitic coupling of film capacitors to other components of the filters and to other elements of the electronic system such as wires and enclosures. Information about the internal structure of the capacitors is taken into account to create accurate and computationally efficient 3D models.
