“…The hardware setup for the experiment consists of a UCC28258/UCC28220 dual interleaved PFC pre-regulator including two CTX16-17309 produced boost inductors as shown in Figure 10 An EMI filter has been installed in the PFC converter to suppress the EMI noise generated by the fast-switching devices. The time-domain EMI measurement system [22], which is simple and efficient will be used to do the spectrum analysis in the experiment. The EMI noise emitted from the PFC converter is captured from the line (L) and neutral (N) output of the LISN.…”

Abstract:A power factor correction (PFC) converter with interleaved multi-channel topology is gaining increasing attention due to its ability in reducing input and output current ripples, but an Electromagnetic Interference (EMI) noise filter is still required for suppressing the large high-frequency switching noise that could potentially degrade the input power quality of the supplying grid and cause malfunctions to other grid-connected systems. In this paper, a magnetic modeling of an interleaved PFC converter with an input differential mode (DM) EMI filter has been successfully implemented, which considers the nonlinear behavior of the inductive component in the EMI filter. The Jiles-Atherton (J-A) model is applied to describe the filtering inductor whose core displays saturation and hysteresis. The simulation results are verified with the experimental test.

“…Later, the errors due to the frequency dependence of the antenna factor, the attenuation in the transmission line, the gain of the preamplifier, the frequency response of the anti-aliasing filter are corrected. Next, a mathematic emulation of the peak, RMS, average and quasi-peak detectors is made, either by applying a correction factor dependent on the pulse repetition frequency [11] or by means of the application of a digital infinite impulse response filter [12]. Additionally, other signal processing techniques can be used in order to reduce the impact of the noise but this has varied upon specific implementations.…”

Abstract-This paper presents a measurement system intended to be used to assets the radiated electromagnetic interference (EMI) in both time and frequency domains. In order to keep the measurement setup as accessible and practical as possible, the direct measurements are recorded with a general purpose digital oscilloscope and processed with a commonly available personal computer. The measurement system was validated for radiated emissions testing using well-known, controlled transient and continuous signals emulating typical interferences. The results are in satisfactory agreement with those provided by a conventional EMI receiver for different types of detectors. The proposed approach shows that, currently, it is possible to implement a timesaving, accurate and generally inexpensive time domain measurement system for radiated emissions that is capable to overcome the limitations of the superheterodyne EMI receivers regarding the measurement of discontinuous electromagnetic disturbances and also able to provide additional enhanced features to evaluate and troubleshoot EMI problems.

Electro-magnetic fields resulting from a GSM transmitter mounted on a large wind turbine will be analyzed. This cellular system operates as novel communication backup in case the standard communication between operator and hub control systems is interrupted. The method-of-moments is used to analytically describe the electro-magnetic fields caused by a GSM 900 MHz transmitter mounted on the hub of a wind turbine. Using a commercial simulation tool the electromagnetic field distribution will be analyzed to determine an optimized wireless communication link to a base station. Different transmitter positions are evaluated based on their radiation patterns. Scattering and diffraction by the turbine's rotation is taken into account.
