A Power-Line Communication System Governed by Loop Resonance for Photovoltaic Plant Monitoring Morales-Aragones, José Ignacio Williams, Matthew St. Michael Kupolati, Halleluyah Alonso Gómez, Víctor Gallardo-Saavedra, Sara Redondo-Plaza, Alberto Muñoz-García, Miguel Ángel Sánchez-Pacheco, Francisco José Hernández-Callejo, Luis Resonancia Within this paper, a PLC system that takes advantage of the loop resonance of an entire DC-PV string configured as a circular signal path is developed and implemented. Low cost and extremely simple transceivers intended to be installed within each PV module of a string have been designed and successfully tested. In addition, an anti-saturation coil has been conceived to avoid saturation of the core when the entire DC current of the string flows through it. Bi-directional half-duplex communication was successfully executed with up to a 1 MHz carrier frequency (150 kbps bitrate), using a simple ASK modulation scheme. The transmission and reception performance are presented, along with the overall system cost in comparison to the previous literature 2023-02-07T12:44:15Z 2023-02-07T12:44:15Z 2022-11-24 journal article Köntges, M.; Kurtz, S.; Packard, C.; Jahn, U.; Berger, K.A.; Kato, K.
