Title
(EN) AC/DC ELECTRIC VOLTAGE CONVERTER
(FR) CONVERTISSEUR DE TENSION ELECTRIQUE ALTERNATIF/CONTINU
Abstract
(EN)
The invention concerns an AC/DC electric voltage converter comprising a bridge rectifier assembly (2) associated with a capacitor (1) and followed by a DC/DC converter (3). The bridge consists of controlled switches (6), in particular MOS transistors, and the capacitor is arranged upstream of the bridge, in parallel on the alternating current supply. The MOS transistors can be switched when the alternating current supply is at crossover. The invention is applicable to the supply of non-resistive loads.
(FR)
L'invention concerne un convertisseur de tension électrique alternatif/continu comprenant un montage redresseur en pont (2) associé à un condensateur (1) et suivi d'un convertisseur continu/continu (3). Le pont est formé d'interrupteurs commandés (6), notamment des transistors MOS, et le condensateur est disposé en amont du pont, en parallèle sur l'alimentation alternative. Les transistors MOS peuvent être commutés lors du passage à zéro de la tension alternative. Application à l'alimentation de charges non résistives.
