“…Two main types of coupling circuits are available to be used in the deployment of PLC Technology: (i) the transformless coupling circuit that does not assure any electrical isolation between the modem and the main electrical network . They are, in general, T or PI shaped, and (ii) the coupling circuit with a transformer that presents a typical isolation between the modem and the electrical network . Coupling circuit with a transformer is the most investigated type due to the isolation it provides and its ability to provide accurate impedance matching.…”

After more than two decades since intensive research began on power line communications (PLC) technology, this interesting field of telecommunication engineering is still progressing towards maturity. Despite some factors that delay its worldwide acceptance, its implementation is starting to take off. Research in PLC is motivated (i) by many factors such as the crowded radio frequency spectrum that requires to be sustained by alternative technologies and (ii) by the emanation of other new technologies that may help PLC to extend its practical implementation such as visible light communications or other wireless communication technologies like near‐field communications. PLC technology is used in applications requiring both low and high data rate but traditionally exploited in applications in which the node does not move. Nowadays, PLC has become widely accepted; hence, a review of the technology may be useful to keep the readers aware of new updates. In this paper, we provide an overview of the evolution of PLC technology over the last few decades.

“…The distributed capacitance between the winding turns acts as a shunt capacitor on the inductor resulting in the occurrence of resonance at a given frequency. Furthermore, the inductive PLC coupler shows good performance in low impedance power cable and yields low energy radiation [102]. The coupling efficiency varies according to distinct factors such as the shape and magnetic characteristics of the magnetic core, the length of the gaps and the characteristic impedance of power cable [102].…”

“…The PLC system has a range of frequency bands allocated to narrowband and broadband PLC data communications. Therefore, PLC couplers can be classified as narrowband (frequency range between 0 kHz and 500 kHz) [38], [52] and broadband (frequency range from 1.7 MHz to 500 MHz) [102], [118]. The frequency bandwidth is determined by low and high cut-off frequencies at 3 dB attenuation and can be modified in function of filter design.…”

The advent of power line communication (PLC) for smart grids, vehicular communications, internet of things and data network access has recently gained ample interest in industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling between the power line and PLC transceivers has become a very important issue. Coupling devices used to inject or extract data communication signals into or from power lines are very important components of a PLC system. There is, however, an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review of couplers, which are required for narrowband and broadband PLC transceivers. Prevailing issues that protract the design of couplers and consequently subtended the inventions of different types of couplers are clearly described. We also provide a useful classification of PLC couplers based on the type of physical couplings, voltage levels, frequency bandwidth, propagation modes and a number of connections. This survey will guide researchers, as well as designers alike, into a quicker resourcing when studying coupling in narrowband and broadband PLC systems.

“…There are studies covering coupling circuits for narrowband (NB) (10-500 kHz) and broadband (BB) (5-15 MHz) PLC systems [15,16]. However, to the best of our knowledge, there is a lack of studies on PLC coupling circuits for ultra-narrowband (UNB) PLC systems, which are characterized by meager data rates, the use of frequencies below 3 kHz, and distances up to 150 km [17].…”

This paper introduces an analog notch filtering-based coupling circuit for receivers in ultra-narrowband and narrowband power line communication systems, which are connected to low-voltage electric power grids. It is composed of a twin-T notch analog filter, which is responsible for imposing a significant attenuation on the main frequency (i.e., f0∈{50,60} Hz) in cascade with an elliptic low-pass analog filter, designed with a 3 dB cut-off frequency of fc≫f0. For f0=60 Hz and fc=2 MHz, the prototype of the analog notch filtering-based coupling circuit attains attenuation values of 22 dB and less than 2 dB at the main frequency and in the rest of the frequency bandwidth, respectively, when practical scenarios are considered. Lastly, it shows that the analog notch filtering-based coupling circuit is more effective than a typical capacitive coupling circuit when frequencies lower than 3 kHz are considered for data communication and sensing purposes.
