“…Also in comparison with the results of the fixed spreading factor technique presented in [8] the "Sine_PAM" has better results and lower FER than most of them. The level-shifted "Sine_Sine" combination causes data losses at low frequencies.…”

“…One of the main advantages of PLC is that it does not require extra installation costs as it uses the existing electrical network to transfer the data [6]. However, PLC systems suffer from the noises conducted by the surrounding electrical equipment [8][9][10].…”

“…On the other hand, the power converters conducted/radiated emissions affect the PLC significantly as the PLC operates in CENELEC-A which operates within 3 -95 kHz while most power converters operate at switching frequency below 150 kHz. Also, the civilian electromagnetic compatibility standards cover the converters operating after 150 kHz [8]. Operating at similar frequency ranges makes the power converters conducted/emitted electromagnetic interference (EMI) adversely affect the PLC system and cause lot of losses in the received data, service misreading, and interruption of service [10].…”

With the expansion of the smart grid, smart meters became played a vital role in monitoring and supervising the grid system. To ensure the continuity of the monitoring and controlling of the smart meters, it's essential to ensure that the communication system operates properly. However, smart meters communication modules face interfering noises from the surrounding equipment. Those interfering noises can adversely affect the communication systems and cause loss of data. This paper introduces chaotic spread spectrum techniques aimed to reduce the interfering noises produced by DC-DC buck converter on G3 power line communication system.

This contribution evaluates the vulnerability of narrowband power line communication in the kHz frequency range through the implementation of frequency swept pulse intentional electromagnetic interference (IEMI) in the MHz frequency range. For this experiment, different types of digital modulation as well as different types of transmission mode are evaluated. The data frame error rate of the transmitter and receiver are compared when a low power frequency-swept pulse IEMI is coupled to the G3 power line communication. Finally, a mitigation plan to manage the risk of intentional EMI in power line communications is recommended.

“…THE measurement of conducted emissions for DC power converters is a topic that has been increasingly investigated, mainly due to its adverse effect on communication links in the low frequency range [1], [2]. The evaluation of the band below 150 kHz is receiving more and more attention, predominantly, due to the conducted Electromagnetic Interference (EMI) for equipment and systems that are part of newly proposed DC microgrid topologies [3].…”

This paper demonstrates that using conventional frequency scanning methods for the evaluation of conducted electromagnetic interference generated by DC/DC converters can give misleading results when pseudo-random modulation is used as part of the converter control scheme. The paper therefore proposes that the resolution bandwidth of the super heterodyne EMI test receiver used for measurements and the dwell time should be adjusted to match the control parameters of the random modulation scheme. The use of different values for resolution bandwidth and dwell time is demonstrated and measurements for random and fixed modulation schemes are compared.
