Abstract

Abstract Translated from French L'invention s'applique à des alimentations à découpage pouvant par exemple alimenter des circuits récepteurs de télécommande d'un téléviseur alors que les autres circuits sont en état de veille. The invention applies to switching power supplies which can, for example, supply remote control receiver circuits for a television while the other circuits are in standby state. Selon l'invention, on modifie toutes les tensions, y compris celle alimentant en service normal les récepteurs de télécommande, mais on commute simultanément la connexion alimentant lesdits récepteurs vers une source de tension plus élevée. Ceci est possible au moyen d'un unique interrupteur si la tension mesurée pour actionner la régulation est précisément celle de la connexion alimentant lesdits récepteurs. According to the invention, all the voltages are modified, including that supplying the remote control receivers in normal service, but the connection supplying the said receivers is simultaneously switched to a higher voltage source. This is possible by means of a single switch if the voltage measured to activate the regulation is precisely that of the connection supplying said receivers.
