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.
本文开发并实现了一种利用整个直流光伏串配置为环形信号路径的环路谐振的 PLC 系统。设计并成功测试了旨在安装在串中每个光伏模块内的低成本、极其简单的收发器。此外，还设计了一个反饱和线圈，以避免当整个串的直流电流流过它时铁芯饱和。使用简单的 ASK 调制方案，以高达 1MHz 的载波频率（150kbps 比特率）成功执行了双向半双工通信。本文介绍了传输和接收性能，并与之前的文献相比给出了整个系统的成本。
