Abstract

In this paper the equivalent circuit model of ferrite EMI Suppressor and its elements will be introduced. In addition, simulation tool Doubleind for calculation of impedance of ferrite EMI suppressor will be presented. It can be used for multilayer inductors, which consists of conductive layers in soft ferrite material. The impedance can be calculated for a few different ferrites and conductive pastes. Two-layer meander type structures of suppressors are proposed. Comparison of proposed and one-layer suppressors has shown that the impedance of proposed will be more than twice greater.
