摘要： A splitter includes, in parallel between trunk terminals and branch terminals, a signal branching circuit that blocks distributed power and passes a PLC communication signal and a power branching circuit that blocks the communication signal and passes the distributed power. In the signal branching circuit, impedance viewed from the branch terminal side is matched with characteristic impedance of a power line and impedance viewed from the trunk terminal side is higher than impedance viewed from the branch terminal side, in the frequency band of the communication signal. In the power branching circuit, input/output impedance is set to be sufficiently higher than the impedance of the signal branching circuit viewed from the trunk terminal side, in the frequency band of the communication signal.

摘要： The object of the invention is to propose a communication system using an electronic choke circuit which has impedance slightly varied with a load variation and is prevented from having negative resistance and can stabilize circuit operation. A terminal device includes an electronic choke circuit separating DC power supplied from a management device and a communication signal from each other. The electronic choke circuit includes a variable impedance element constituted by a transistor having its collector and its emitter respectively connected to a first terminal and a third terminal, and an inductor and a resistor connected in series with the variable impedance element. A series circuit of a first resistor and a first capacitor is interposed between the first terminal and a second terminal, and the first capacitor has its one end connected to a base of the variable impedance element. A second capacitor is interposed between the third terminal and a fourth terminal. A second resistor suppresses a phenomenon that resistance characteristics of a circuit between an input terminal and an output terminal have a negative resistance region within a frequency band including a frequency of the communication signal.
