Abstract
A control system includes a control device adapted to be connected to a live line and a neutral line that transmit a grid power, and to a load via a first power line and a second power line. The control device includes: a first switch adapted to be connected between the live line and the first power line; a second switch adapted to be connected between the neutral line and the second power line; a coupler adapted to be connected to the first power line, receiving a communication signal, and coupling the communication signal to the first power line; and a controller controlling the first and second switches to synchronously alternate between an ON state and an OFF state, and outputting the communication signal to the coupler when the first and second switches operate in the OFF state.
