Opis:
Most automotive electronic components can cause electromagnetic interference, that can cause power electronic circuits to become unstable. As per electromagnetic compatibility (EMC) standards, these electronic circuits should meet the specifications which are not achieved under some conditions. In this paper, the conducted emissions (CEs) are generated due to the switching of a buck converter, which often occurs in automotive electronics. The noise source was found to be due to the presence of common mode currents which largely affects the performance of EMC. Two types of filtering techniques were analysed and designed, and the results were compared to find an effective filtering solution to mitigate the effects of CE due to a common mode noise for the frequency range from 150 kHz to 108 MHz according to the International Special Committee on Radio Interference (CISPR25) standard. The capacitive and parasitic impedance were calculated and then used in the simulation. Finally, the simulated and measured results are presented. The noise level can be minimized by as much as 50 dB, which is an efficient noise reduction value.

Opis:
In Introduction are introduced main problems of measurement of EMI filter and is suggested that creation of model of EMI filter is useful. In this paper is shown model of EMI filter which is based on basic circuitry of the EMI filter. Reduced equivalent circuitries for EMI filter and his creation are also shown, because these circuitries are more suitable for usage in iteration optimization loop. The spurious elements of filter are searched with optimization. Participial swarm optimization is used. Two possibilities of fitness function calculations are shown, too. Results of both approaches are compared in this paper. Using fitness function with weight coefficients gives better results and this fitness function is used for optimization of the measured characteristics.

Opis:
In this paper we proposes a synthesis of different mathematical models of power electronic converters based on Thevenin/Norton equivalent circuits. Those models, composed by impedances and harmonic noise sources, are helpful to predict the conducted ElectroMagnetic Interferences (EMI) generated by converters connected to the electrical network. Moreover, the extracted impedances are determining for sizing EMC filters. The proposed analytical model is tested with PSpice simulations and validated by experimental measurements, from DC frequency until 30MHz.
