Title (EN) SINGLE-PHASE RECTIFIER
(FR) REDRESSEUR MONOPHASE
Abstract:
(EN) A single-phase rectifier wherein: a full-wave rectifying circuit (3) is connected to a single ac power supply (1) through a reactor (2); a pair of smoothing capacitors (5) is connected in series between the output terminals of the circuit (3); a pair of diodes (4) connected in series is connected in parallel to the series capacitor circuit (5); the node of the paired diodes (4) is connected to the node of the paired smoothing capacitors (5); and an ac capacitor (6) is inserted between one of the input terminals of the circuit (3) and the node of the paired smoothing capacitors (5). As a result, the single-phase rectifier can be manufactured in a smaller size and at a reduced cost as a whole.
(FR) Dans ce redresseur monophasé, un circuit redresseur pleine onde (3) est relié par un réacteur (2) à une alimentation électrique à courant alternatif monophasé (1), deux condensateurs de filtrage (5) sont connectées en série entre les bornes de sortie du circuit (3), deux diodes (4), connectées en série, sont reliées en parallèle aux condensateurs connectés en série (5), le noeud des diodes jumelées (4) est relié au noeud des condensateurs de filtrage (5) et un condensateur à courant alternatif (6) vient se placer entre l'une des bornes de sortie du circuit (3) et le noeud des condensateurs de filtrage jumelés (5). Cet agencement permet d'obtenir un redresseur monophasé de petite taille et à un prix de revient réduit.
