摘要： PROBLEM TO BE SOLVED: To simplify the connection of a device which superimposes a signal on a power line in power line communications.
SOLUTION: A modem 8 is connected to wiring lines 5 and 7 at a position where line length whose maximum wavelength is 1/100 or more and less than 10 m of a high frequency signal to be used by modems 8 and 13 is isolated from a low voltage side connection terminal 3a of a transformer 3. This line length results in the appearance of the characteristic impedance, and handles the line as a distribution constant circuit. Thus, currents flow through both of them (transformer 3 and the other modem 13) when it is viewed from the signal injection point of the modem 8, and to perform power line communications.
