Abstract
This invention focuses on a power line communication (PLC) device that is particularly suitable for Home automation systems and for solar panel systems. The device comprises a modem, a power supply to power said modem from an AC power line and a coupling device to communicate via the power line. The coupling circuit comprises a serial LC filter (C1, L1) and a shunt element (42). The shunt element (42) comprises a rectifier (21) that is connected to the power supply. The present invention provides a novel synergy between the coupling device and the power supply of the modem. The invention provides a power line communication device that is more compact and less expensive than conventional PLC devices.
