About 10 years ago the disturbance scenario between a powerline-communication system (PLC) and a short wave receiving station has been presented [1, 2]. This showed a significant influence on the signal to noise ratio. In the mean-time the channel model, coding and data transmission rate of broadband PLC systems have been considerably improved. Furthermore the national and international standardization has been changed. Based on these developments this paper provides an update for the influence of state-of-the-art broadband inhouse PLC on the short-wave reception from EMC point-of-view and given physics [3]. Measurements in two different electromagnetic environments will be presented. This is complemented by an overview of currently used standards and typical applications.

Operational uncertainties such as variation of power or grid impedance affect the level of conducted emission of power converters in renewable energy systems. This paper utilizes an enhanced Unscented Transform (UT) method based on dimension reduction technique to predict the conducted emissions of multiple Voltage Source Converters (VSCs) in the presence of uncertainties. The accuracy of the predicted results are then compared with the Monte Carlo Simulation approach and the traditional Unscented Transform.

In this work we investigate the Electromagnetic Compatibility of an instrumented rotor blade. Particularly, the cross coupling between lightning conductor and signal lines within the rotor blade is calculated. Here, we use the well-known theory of multiconductor transmission lines. The calculations are compared with simulations. Generally, a very good agreement can be observed. Further, the efficienc of several EMC measures like twisting and shielding is analyzed. Finally, an appropriate separation distance is estimated to avoid voltage flash vers.

Carbon fiber reinforced polymers (CFRP) find increased applications in the aerospace field because of their high strength and light weight. In this work, we report comprehensive electromagnetic compatibility (EMC) modeling, analysis and characterization of a newly developed nanocomposite CFRP with enhanced conductivity for aeronautic applications. The EMC modeling and analysis are performed for lightning strike protection (LSP) simulation and high intensity radiation field (HIRF) study of CFRPs. The LSP simulations are conducted both in time and frequency domains by using dynamic and static electromagnetic tools. And the HIRF is studied for its impact on shielded and unshielded cables in an CFRP enclosure. In addition, we present experimental characterization results of CFRPs.

The railway environment is very rich in terms of electromagnetic disturbances. The variety of the transient and permanent interferences and the current evolution of the communication and signaling railway systems require the adaptation of EMC railway standards. In particular, standardized emission measurement methodologies are not fully adapted to measure transient interferences which can significantly affect new railway signaling and communication systems. In this paper, we study a new time-frequency processing specifically designed for railway EMC issues, which could be implemented on real time spectrum analyzers. A flexible methodology is proposed offering an optimum analysis in relation with the technical specifications of the different railway signaling and communication systems.

Recent studies have shown a high interest in statistical methods dedicated to the prediction of the maximum confidence in simulation and measurements for Electromagnetic Compatibility. In particular, it has been shown that one of the main issues remains the access to a number of samples allowing estimating the risks with regard to the test set-up random variables. In this paper it is argued that re-sampling techniques, also called bootstrapping procedures, enable to optimize the number of experiments while estimating the maximum confidence level of the accessible samples.

CISPR has defined a standard regarding the radio-frequency disturbance level of appliances (CISPR 14-1). The scope of this standard is to worldwide fix disturbance limits and standardise methods of measurement, operating conditions, and interpretation of results. Today, there exist special discontinuous disturbance analysers (“click analysers”) that perform both measurements and analysis. However, the analysis performed by some click analysers is not in accordance with the procedure defined in the CISPR 14-1 standard. This leads to appliances on the market being incorrectly declared CISPR 14-1 compliant. The intention of this article is to address and clarify possible misinterpretations of the CISPR 14-1 measuring procedure of discontinuous disturbances.

A general method for determining the number of independent stirrer positions in reverberation chambers has been presented in previous papers. For this method, the field distributions within a defined test volume are measured for a given number of points and as a function of the stirrer position. The field distributions of the stirrer positions used are tested for linear correlation using the Pearson correlation coefficient and a correlation threshold that is adjusted to the number of points used for the test volume. Based on the calculated correlation coefficients and a specially developed algorithm, the number and distribution of the independent stirrer positions are determined. In this paper, the evaluation of the general method is continued. The independent stirrer positions are evaluated based on the field homogeneity in the reverberation chamber.

Coupled Inductors are widely used in EMI power filters. The impact of temperature on the frequency behavior of these components is very significant and shouldn't be neglected. In this paper, characterization test-benches and modeling methods of coupled-inductor impedances via measurements are presented for two types of magnetic cores: nanocrystalline alloy and Manganese-Zinc (Mn-Zn) ferrite. The aim of this study is to propose relatively simple models in order to estimate the thermal behavior of these components by simulation, for frequencies ranging from 10 kHz up to 100 MHz and temperatures ranging from -40°C up to 200°C. The new model is simulated and the obtained results are compared to the experimental measurements in the frequency domain. The developed model is then translated to VHDL-AMS language for easy implementation in most electrical simulation softwares.

Chokes are crucial in power electronics applications to block the propagation of high-frequency disturbances produced in switching events. At high frequencies, the real behavior of a choke can differ significantly from its nominal behavior due to the frequency-dependency of core materials and due to parasitic couplings introduced by the windings. This paper presents an accurate, versatile, and computationally efficient method to compute the parasitic couplings and predict the frequency-dependent impedance of the choke. Comparison with measurements of sample chokes with ferrite and nanocrystalline cores show excellent agreement in the entire EMC frequency range of 150 kHz to 30 MHz. Multiple self-resonances of the choke can be correctly described.
