“…In response to this, the IFBW selection is one essential factor for emulating the EMI receiver accurately. Details about standardized EMC measurement has been elaborated in [12,23]. Figure 3b shows the representation of high frequency output signal of a compact fluorescent lamp in time-domain, it consists of different frequency in each oscillating cycle inversely proportional to its amplitude, and Figure 3d is the measured conducted emission in frequency-domain.…”

This paper presents the measurement of aggregated conducted emission in the frequency range of 9 kHz to 150 kHz produced by multiple compact fluorescent lamps (CFL) and how it equates to a multiple power converter system. Discrepancies in peak emission measurement results related to this application are illustrated to understand the underlying issue related to volatility of frequency components. Furthermore, this knowledge analyzes the relation of electromagnetic disturbances with respect to different topological network connections. The final presented results constitute theoretical description and statistical information about the characteristics of conducted emission measured in this multi-converter system.

“…Some cases of the malfunction of the PLC also have been reported in several countries by [3] and [6]. These reports also show that some of the available commercial LED lamps have emission levels that exceed the maximum emission limit defined in the EN55015 standard [11]. The non-linear characteristic of the LED lamps creates impulsive currents which can cause errors in the data transmission of the narrowband PLC.…”

This paper presents the impact of LED lamps on the performance of Narrowband Power Line Communication (NB-PLC) in the CENELEC-A band between 9-95 kHz. NB-PLC in is only one of the many victims of interference in the frequency range 2-150 kHz. Only few emission standards for this frequency range are available, while the number of interference cases is growing rapidly. Most equipment will fail at a specific frequency and/or level. PLC is chosen as a victim, as the performance of the PLC is rated through well-established parameters. One of these is the Frame Error Rate (FER), which is calculated as the ratio between the erroneous frames and total received frames. The number of LED lamps has a strong correlation with the peak amplitude of the current pulses from the LED lamps and the FER of the PLC data frames.

“…Subsequently the DC-DC convertor noise travels through the rectifier (when a rectifying diode is conducting) and presents itself on the line currentsuperimposed on the nonlinear rectifier current shape. EMI Filters are used to mitigate noise to below compliance levels [15]. These filters reduce noise from two noise sources.…”

Light Emitting Diode (LED) lamps are used as a replacement of "old-fashioned" or incandescent lighting sources, as they reduce the amount of energy consumed. As a sideeffect of more efficient energy usage they produce electrical noise. This noise reduces the efficiency of information signal transfer when Power Line Communications (PLC) are used. This study focuses on the noise signatures of LED lamps which have a direct impact on the information transfer of the PLC channel. The contribution of this study is that two categories of noise characterisations are given. First is equations describing the maximum and minimum bounds of the lamp noise current. This is useful in calculating channel throughput where an equation for the noise is required. For example, the Shannon-Hartley theorem. Second is a methodology to determine individual frequencies in the spectrum of harmonics emanating from the lamp. Both these characterisations will aid in designing communication schemes for PLC. An unexpected result of this study was to find LED lamps which had inadequate or no Electromagnetic Interference (EMI) filters. These lamps produce noise in orders of magnitude higher than properly filtered LED lamps.
