PROBLEM TO BE SOLVED: To provide a load drive system capable of configuring a power line communication network connecting loads such as actuator without lowering communication speed at a low cost.SOLUTION: The load drive system for driving loads which are supplied with electric power via a power line, includes: a control unit configured to control switching operation between the power line and the load; and a communication part configured to carry out communication using voltage and current from the power line. The control unit is configured so as to, when carrying out the switching operation, control the timing to carry out the switching operation so that the transition period gets separated away from the center of the period of time equivalent to a symbol communicated by the communication part on the basis of the width of the transition period of the current on the power line caused by the switching operation.SELECTED DRAWING: Figure 1

    【課題】アクチュエータ等の負荷を接続する電力線通信ネットワークを通信速度の低下なく低コストに構成する。【解決手段】電力線から電力を供給される負荷を駆動する負荷駆動システムであって、前記電力線と前記負荷との間のスイッチングを制御する制御部と、前記電力線の電圧及び電流を利用して通信する通信部と、を有し、前記制御部は、前記スイッチングを行う場合に、前記スイッチングに起因する前記電力線の電流の遷移期間の幅に基づいて、前記遷移期間を、前記通信部によって通信されるシンボルに相当する期間の中心から遠ざけるように、前記スイッチングを行うタイミングを制御する。【選択図】図1
