ALIMENTATION CONTINUE BASSE TENSION POUR DISPOSITIFS ELECTRONIQUES DE COMMUNICATION

摘要

The present invention relates to a system (100) for supplying low-voltage DC power to at least one electronic communication device (3;6) in a power line carrier communication system furthermore including a power line carrier coupler comprising a coupling capacitor (10) electrically linked to a medium-voltage line (8) of a power distribution network. According to the invention, the system (100) comprises means (15) for generating a first low DC voltage value based on a current-to-voltage conversion of the leakage current related to said coupling capacitor (10), said first low DC voltage value being able to act as power supply to at least one active electronic component (13) of said at least one electronic communication device (3;6).
