摘要

Traditional EMI filters (ElectroMagnetic Interference), used to reduce differential (DM) and common mode (CM) noise flowing from SMPS (switching-mode power supply) to aircraft power network, has become a major issue to reduce the volume of power electronics equipment. New EMI filters based on a single component and able to reduce the both modes are proposed. To study such components, we need to take care of the DO-160 standard which imposes attenuation level and magnetic material performance in a large frequency range (10 kHz to 100 MHz). To predict and optimize the behaviour of the filter, an original computation model is developed. It is based on lumped electric, geometric and magnetic parameters and can even take into account the complex permeability behaviour with frequency. This tool, should allow the EMI filters performance to be improved. with respect to the DO-160 standard.
