(EN) VOLTAGE CONVERTER
(FR) CONVERTISSEUR DE TENSION
Abstract
(EN)
The invention relates to a voltage converter (1) receiving as input a primary DC voltage (2) that is variable within in a large voltage range, and outputting a first regulated secondary DC voltage (3) and a second non-regulated secondary DC voltage (4), comprising a buck converter with a choke coupled to two outputs (5), characterized in that it further comprises a boost converter (6) arranged upstream from the buck converter (5) suitable for raising the primary voltage (2) when activated and a charge pump module (7) arranged between the second secondary voltage (4) and the first secondary voltage (3) suitable for balancing the loads when activated, the activation of the boost converter (6) and of the charge pump module (7) being simultaneous.
(FR)
L'invention concerne un convertisseur de tension (1) recevant en entrée une tension primaire (2) continue, variable dans une grande étendue de tension, et fournissant en sortie une première tension secondaire (3) continue régulée et une deuxième tension secondaire (4) continue non régulée, comprenant un convertisseur buck à self couplées à deux sorties (5), caractérisé en ce qu'il comprend encore un convertisseur boost (6) disposé en amont du convertisseur buck (5) apte à relever la tension primaire (2) lorsqu'activé et un module pompe de charge (7) disposé entre la deuxième tension secondaire (4) et la première tension secondaire (3) apte à équilibrer les charges lorsqu'activé, l'activation du convertisseur boost (6) et du module pompe de charge (7) étant simultanée.
