Control of cascaded H-bridge converters for power line communicationControl of cascaded H-bridge converters for power line communication Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2024-12-102022enPower line communication (PLC) technological advancements are currently being led by the interoperation needs in applications such as smart grids, building energy management systems, electric vehicles, and the Internet of Things. In this paper, alternative control schemes are proposed and compared for the simultaneous transmission of power and digital data through the power circuits of the modules synthesizing a single-phase cascaded H-bridge multilevel inverter. The proposed PLC method does not require any additional circuit elements in the power loop for the PLC implementation. Special focus is paid to the control schemes applied to the H-bridge driving circuits to produce a low total harmonic distortion (THD) without compromising the reliability of data communication. Various parametric simulation models are designed and tested using time-division multiplexing with two variations over the assignment technique for the PLC communication task. The results suggest that the proposed low-bandwidth PLC design is robust enough to provide the required communication fidelity and capable of successfully transmitting the mixed-signal (i.e., power and data) through the power cable under various operating conditions.This research has been co‐financed by the European Regional Development Fund of the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH–CREATE–INNOVATE (project code: T1EDK-01485).http://creativecommons.org/licenses/by/4.0/48th Annual Conference of the IEEE Industrial Electronics SocietyProceedings of the 48th Annual Conference of the IEEE Industrial Electronics Society Mandourarakis Ioannis Μανδουραρακης Ιωαννης Koutroulis Eftychios Κουτρουλης Ευτυχιος Karystinos Georgios Καρυστινος Γεωργιος Institute of Electrical and Electronics Engineers Power line communication Total harmonic distortion Multilevel inverter Cascaded H-bridge Sinusoidal pulse width modulation
