THE EMBEDDED TYPE OF AN INDUCTIVE COUPLER FOR POWERLINE COMMUNICATION

摘要

An embedded contactless signal coupling apparatus having a PLC modem built-in for PLC is provided to simplify a communication system and improve installation workability by embedding the PLC modem inside a signal coupling apparatus. A contactless signal coupling apparatus comprises an impedance matching circuit(200), a low, high, or band pass filter(300), a signal amplification device(400), a PLC modem(500) and a self power supply apparatus. The low, high, or band pass filter removes the noises of the communications except signal. The signal amplification device compensates for the signal transmission loss generates during the magnetism process of induction. The output power of the self power supply apparatus is used as the drive power of the PLC modem.
