Abstract
Devices and system for interfacing multiple power line communications (PLC)-enabled communication devices in a building are disclosed. In various embodiments, the system can include a high-frequency transformer coupled to a high-frequency communications device, a low-frequency transformer coupled to a low-frequency communication device, and one or more components adapted to appreciably abate distortion and/or attenuation of high-frequency signals passing through the first coupling device.
Claims17
A coupling system for interfacing a high-frequency power line communications (PLC)-enabled communication device and a low-frequency PLC-enabled communications device with a low-voltage power network, the system comprising:
- a first coupling device that includes a high-frequency transformer having a first primary side and a first secondary side, wherein the first primary side is electrically coupled to the high-frequency communications device, and the first secondary side is capacitively coupled to a first power line of the power line network via a first capacitor;
- a second coupling device that includes a low-frequency transformer having a second primary side and a second secondary side, wherein the second primary side is electrically coupled to the low-frequency communication device, and the second secondary side is capacitively coupled to the first power line of the power line network via a second capacitor;
- wherein the second coupling device is adapted to appreciably abate at least one of distortion and attenuation of high-frequency signals passing through the first coupling device.
