摘要

本文研究了开关电源的传导辐射问题。它旨在优化输入EMI(电磁干扰)滤波器的尺寸。在时域和频域上采用了G.Kron提出的基于多物理和多尺度方法的拓扑方法。采用遗传算法对滤波器的物理尺寸进行优化。因此,由于波形估计和滤波器建模,EMI滤波可以在设计阶段考虑。

SMPS Tools for EMI Filter Optimization
This paper deals with conducted emissions in SMPS (Switched Mode Power Supplies). It aims to optimize the size of the input EMI (Electro-Magnetic Interference) filter. A topological method worked out by G.Kron, based on multiphysical and multiscale approach, is used in time and frequency domains. A genetic algorithm is also used to optimize the physical dimensions of the filter. Thus, thanks to waveform estimations and the filter modelling, EMI filtering can be taken into account at the design stage.
