Title (EN) ENERGY SAVING STARTUP CIRCUIT FOR POWER SUPPLY
(FR) CIRCUIT DE DEMARRAGE A ECONOMIE D'ENERGIE POUR ALIMENTATION ELECTRIQUE
Abstract:
(EN) A startup circuit (30) for a power supply (44), has an input (31) for connecting a source of high voltage thereto, and an output rail (33) for feeding rectified voltage to the power supply. A first energy storage device (35) is coupled to the output rail for storing energy when voltage is first applied to the input, and a second energy storage device (37) is coupled to an output of the power supply for storing energy when a voltage appearing at the output of the power supply reaches substantially steady state. A switching circuit (36, 50) is coupled to the first energy storage device and to the second energy storage device and is responsive to the first energy storage device having sufficient energy for transferring the energy to the second energy storage device and disconnecting the first energy storage device from the output rail.
(FR) La présente invention concerne un circuit de démarrage (30) destiné à une alimentation électrique (44) qui possède une entrée (31) destinée à connecter une source de haute tension et, un flux de sortie (33) destiné à alimenter en tension rectifiée cette alimentation électrique. Un premier dispositif de stockage d'énergie (35) est couplé au flux de sortie de façon à stocker de l'énergie lorsque la tension est d'abord appliquée à l'entrée et, un second dispositif de stockage d'énergie (37) est couplé à la sortie de l'alimentation électrique de façon à stocker l'énergie lorsqu'une tension survenant à la sortie de l'alimentation électrique atteint un état sensiblement stable. Un circuit de commutation (36, 50) est couplé au premier dispositif de stockage d'énergie et au second dispositif de stockage d'énergie et il peut réagir au fait que le premier dispositif de stockage d'énergie possède suffisamment d'énergie pour transférer cette énergie au second dispositif de stockage d'énergie et pour déconnecter le premier dispositif de stockage d'énergie du flux de sortie.
