Title
(EN) METHODS AND APPARATUS FOR HIGH POWER FACTOR CONTROLLED POWER DELIVERY USING A SINGLE SWITCHING STAGE PER LOAD
(FR) PROCÉDÉS ET APPAREIL DE FOURNITURE DE PUISSANCE CONTRÔLÉE À FACTEUR DE PUISSANCE ÉLEVÉ À L'AIDE D'UN ÉTAGE DE COMMUTATION UNIQUE PAR CHARGE
Abstract
(EN)
Methods and apparatus for high power factor power transfer to a load using a single switching stage. In exemplary implementations, a controllable variable power may be delivered to a load using a single switching stage while maintaining high power factor, in some cases without requiring any feedback information relating to the load conditions (i.e., without monitoring load voltage and/or current) to control normal switching operations in the single switching stage, and without requiring regulation of load voltage and/or load current. In one example, a single stage high power factor driver is used to control power delivery to an LED-based light source.
(FR)
L'invention concerne des procédés et un appareil de transfert de puissance à facteur de puissance élevé vers une charge à l'aide d'un étage de commutation unique. Dans des modes de réalisation, une puissance variable pouvant être contrôlée peut être fournie à une charge à l'aide d'un étage de commutation unique tout en maintenant un facteur de puissance élevé, dans certains cas, sans nécessiter aucune information de retour quelconque relative aux conditions de charge (c.-à-d., sans surveillance de tension et/ou de courant de charge) pour commander des opérations de commutation normales dans l'étage de commutation unique, et sans nécessiter la régulation de tension de charge et/ou de courant de charge. Dans un exemple, un dispositif de commande de facteur de charge à puissance élevée étage unique est utilisé pour contrôler la fourniture de puissance à une source lumineuse à base de DEL.
