Projeto e Caracterização de Acopladores para Power Line Communications

This paper discusses the project of capacitive cou- plers for Power Line Communications (PLC) in the range frequency of 9 kHz to 500 kHz and 1,7 to 500 MHz for low voltage networks. The use of Microstrip technique to design printed circuit boards and other relevant decisions in the p roject are proposed. The results based on these decisions indicate that the approach discussed in this work can be applied with good results when it comes to matter the safety requirements and t he results obtained in the characterization of PLC couplers.
