Title (EN) PROVIDING HIGH EFFICIENCY IN A POWER SUPPLY OVER A RANGE OF LOAD CONDITIONS
(FR) FOURNITURE D'UN RENDEMENT ÉLEVÉ DANS UNE ALIMENTATION ÉLECTRIQUE SUR UNE GAMME DE CONDITIONS DE CHARGE
Abstract:
(EN) An apparatus, system, and method are disclosed for providing high efficiency in a power supply over a range of load conditions. The apparatus includes a condition module that determines whether the power supply is in a high load state or a low load state. A high load module ensures that the load receives power through the power supply's high load power train if the load state is the high load state. A low load module ensures that the load receives power through the power supply's low load power train if the load state is the low load state. The high load power train is optimized for efficiency under high power conditions, while the low load power train is optimized for efficiency under low power conditions. The power supply thus operates with the most efficient power train for the particular load conditions, improving the net efficiency of the power supply.
(FR) L'invention concerne un appareil, un système et un procédé pour fournir un rendement élevé dans une alimentation électrique sur une gamme de conditions de charge. L'appareil comprend un module de condition qui détermine si l'alimentation électrique est dans un état de charge élevé ou dans un état de charge faible. Un module de charge élevée garantit que la charge reçoit l'énergie via la transmission de charge élevée de l'alimentation électrique si l'état de charge est l'état de charge élevée. Un module de charge réduite garantit que la charge reçoit l'énergie via la transmission de charge réduite de l'alimentation électrique si l'état de charge est l'état de charge réduite. La transmission de charge élevée est optimisée pour fournir un rendement dans des conditions d'alimentation élevée, alors que la transmission de charge réduite est optimisée pour fournir un rendement dans des conditions d'alimentation réduite. L'alimentation électrique fonctionne donc avec la transmission la plus efficace pour les conditions particulières de charge, améliorant le rendement net de l'alimentation électrique.
