Title (EN) DC-DC CONVERTER DEVICE AND METHOD
(FR) PROCEDE ET DISPOSITIF CONVERTISSEUR CONTINU-CONTINU
Abstract: front page image
(EN)An increasing number of phases in multiphase converters causes an increase in requirements with respect to the control IC. According to the present invention, instead of deriving a new PWM signal for every single phase of the DC-DC converter, the single phases are clustered into groups (22, 24, 26). Within each group, the converters are operated on the basis of one PWM signal (PW M1, PW M2…PW MN). Advantageously, this may allow to reduce the requirements with respect to the control IC and thus may allow the application of cheaper and smaller control ICs.
(FR)Le nombre croissant de phases dans les convertisseurs multi-phase entraîne une augmentation des exigences en matière de circuits intégrés de commande. Selon la présente invention, au lieu de dériver un nouveau signal PWM pour chacune des phases du convertisseur continu-continu, les phases uniques sont groupées (22, 24, 26). Au sein de chaque groupe, les convertisseurs sont exploités sur la base d'un signal PWM (PW M1, PW M2 PW MN). Ceci permet avantageusement de réduire les exigences en matière de circuits intégrés de commande, et donc de permettre l'application de circuits intégrés de commande moins chers et plus petits.
