To provide a power line communication apparatus capable of performing communication even when a load current of a load connected to a power line fluctuates.SOLUTION: A power line communication apparatus 1 includes an ECU-side control station 2 that is connected to a pair of power lines 301, supplies a voltage to the pair of power lines, and receives a current flowing through the pair of power lines as data, and an actuator-side slave station 4 that is connected to the pair of power lines and generates a communication current according to transmission data. The actuator-side slave station 4 includes a load current detection unit 407 that detects a load current IL flowing through a load 406 to which a voltage is supplied from the pair of power lines 301, and a correction current calculation circuit 408 that calculates a correction current ICOMP to be supplied to the pair of power lines such that reception in the ECU-side control station 2 is not hindered by a change in the current flowing through the pair of power lines due to a change in the load current.SELECTED DRAWING: Figure 1

    【課題】電力線に接続されている負荷の負荷電流が変動している場合でも、通信が可能な電力線通信装置を提供する。【解決手段】電力線通信装置1は、一対の電力線301に接続され、一対の電力線に電圧を供給し、一対の電力線を流れる電流をデータとして受信するECU側制御局2と、一対の電力線に接続され、送信データに応じた通信電流を生成するアクチュエータ側子局4とを備える。アクチュエータ側子局4は、一対の電力線301から電圧が供給される負荷406を流れる負荷電流ILを検出する負荷電流検出部407と、負荷電流の変動による一対の電力線を流れる電流の変化によって、ECU側制御局2における受信が阻害されないように、一対の電力線に供給する補正電流ICOMPを算出する補正電流演算回路408とを備える。【選択図】図1
