Plug-in single phase power line signal repeater with low voltage bus

摘要

A control system and method suppress noise in a power-line-based system which has a device repeater connected to an electrical device, and which may be capable of remote control by signals transmitted through the power-line-based system. The control system includes a control device and a communications bus. The communications bus connects the control device to the device repeater. The control device, using a control repeater, controls a phase signal of the device repeater to suppress noise during operation of the electrical device associated with the device repeater.
