A method and circuit for reducing power consumption during idle mode to ultra- low levels, such as about 1/10th to 1/1000th or less of active power is disclosed. An ultra-low idle power supply comprises a primary circuit, a secondary circuit and a control circuit. The control circuit monitors behavior of the primary circuit and determines whether an idle state or no load condition exists, and if so the primary circuit is disengaged. By disengaging the primary circuit, the power consumption of the ultra-low idle power supply is reduced to ultra-low levels.
L'invention porte sur un procédé et un circuit destinés à réduire une consommation électrique en mode veille à des niveaux ultrabas, tels quenviron 1/10ième à 1/1 000ième ou moins de la consommation d'énergie en mode actif. Une alimentation à consommation ultrabasse en mode veille comprend un circuit primaire, un circuit secondaire et un circuit de commande. Le circuit de commande surveille le comportement du circuit primaire et détermine si un état de veille ou une situation d'absence de charge existe et, si cest le cas, le circuit primaire est désaccouplé. Par désaccouplement du circuit primaire, la consommation d'énergie de l'alimentation à consommation ultrabasse en mode veille est réduite à des niveaux ultrabas.
