PROBLEM TO BE SOLVED: To implement a satisfactory communication without providing an impedance increase part for each device connected to a power supply line in a power supply line communication system.SOLUTION: A power supply line communication system comprises: a power supply line (12) for supplying power from a DC power source (10) to multiple devices (2A, 2B, ...) including bypass capacitors (4A, 4B, ...); and communication parts (6A, 6B, ...) provided in the devices respectively. A communication frequency of the communication part is set in such a manner that a signal level of a communication signal is prevented from being reduced by impedance reduction of the bypass capacitor in that communication frequency. The DC power source includes impedance increase parts (20 and 22) for increasing impedance at a DC power source side in that communication frequency and suppressing level reduction of the communication signal.SELECTED DRAWING: Figure 1

    【課題】電源線通信システムにおいて、電源線に接続される機器毎にインピーダンス増大部を設けることなく、良好な通信を実施できるようにする。【解決手段】バイパスコンデンサ(4A,4B,…)を備えた複数の機器(2A,2B,…)に対して直流電源(10)から電源供給を行う電源線(12)と、各機器にそれぞれ設けられた通信部(6A,6B,…)とを備える。通信部の通信周波数は、その通信周波数でのバイパスコンデンサのインピーダンス低下によって通信信号の信号レベルが低下することのない周波数に設定され、直流電源には、その通信周波数での直流電源側のインピーダンスを増大させて、通信信号のレベル低下を抑制するインピーダンス増大部(20、22)が設けられる。【選択図】図1
