  • unit 100 may also be configured to return HPAV signals 140 from the STB to the electric mains. Unlike the DC power and zero crossing indications that may flow only towards the STB, HPAV signals 140 may be assumed to be bi-directional, i.e. moving in both directions. Accordingly, HPAV signals 140 may also flow from the STB via wiring 105' through HPF 115, and out to the source of VAC 101 via wiring 105. It will further be appreciated that the designation of such signals as "HPAV" may be exemplary; the present invention may be sufficiently robust to include any powerline based signal.
  • Triple prong input wiring 505 may carry AC current from the electric mains.

  • the neutral and ground wires may be branched in a second pairing and input to a second HPF 315, yielding HPAV signals 340 which may be output on wiring 505' in addition to the signals on wiring 305'.
  • system 500 may provide redundant and/or additional HPAV signals when compared with the previous embodiments.
  • unit 600 may be configured in accordance with the configuration of unit 500. Accordingly, unit 600 may also be configured in a generally similar manner to unit 400 in order to accommodate processing zero cross indications on a dedicated wire if system 500 may be configured in accordance with the embodiment of Fig. 15B.

Abstract

L'invention porte sur une unité d'alimentation qui comprend un convertisseur CA/CC destiné à convertir une entrée VAC en courant continu, une unité de passage par zéro destinée à moduler la sortie du convertisseur CA/CC pour faciliter la détection du passage par zéro sur la base de la sortie, et un filtre passe-haut (HPF) destiné à filtrer des signaux de données, les signaux de données étant émis et reçus sur le même support à partir duquel l'entrée VAC est reçue. L'invention porte également sur un procédé pour fournir des signaux d'alimentation et de données à partir d'une unique source sur courants porteurs, le procédé comprenant la réception d'une entrée VAC dans une unité d'alimentation externe, la conversion de l'entrée VAC en courant continu, la modulation du courant continu conformément aux passages par zéro à partir de l'entrée VAC, le filtrage de l'entrée VAC pour isoler les signaux de données haute fréquence, les signaux de données étant émis et reçus sur le même support à partir duquel l'entrée VAC est reçue, et la fourniture des signaux de courant continu, de courant continu modulé et de données à une unité de traitement incorporée capable de traiter les signaux de données.
