(DE) GLEICHRICHTER MIT HOHEM LEISTUNGSFAKTOR UND WENIG OBERSCHWINGUNGEN
(EN) RECTIFIER WITH HIGH POWER FACTOR AND LOW HARMONICS
(FR) REDRESSEUR AVEC UN FACTEUR DE PUISSANCE ÉLEVÉ ET DES FAIBLES HARMONIQUES
Abstract
(EN)
The present invention discloses a power apparatus with the output voltage thereof made variable, which allows harmonics to be suppressed while an enhanced power factor being maintained. The power apparatus comprises an alternating current power source, a bridge rectifier circuit to subject alternating currents from the alternating current power source to full-wave rectification, a reactor connected between the alternating current power source and the alternating current input end of the bridge rectifier circuit and a capacitor connected via a bi-directional switch between the alternating current input end and the direct current end of the bridge rectifier circuit, further comprising a smoothing capacitor, a zero-crossing detecting means, a bi-directional switch drive signal generating means and a bi-directional switch driving means.

(FR)
L'invention concerne un dispositif de puissance à tension de sortie variable qui permet la suppression des harmoniques et le maintien d'un facteur de puissance élevé. Le dispositif comprend une source d'alimentation en courant alternatif (c.a.), un circuit de redressement en pont pour le redressement pleine onde de c.a. fourni par la source de c.a., un circuit de réactance couplé entre la source de c.a. et l'extrémité d'entrée de c.a. du circuit en pont, un condensateur couplé via un commutateur bidirectionnel entre l'extrémité d'entrée de c.a. et une extrémité de sortie de courant continu (c.c.), un condensateur de filtrage, un détecteur de passage à zéro, un générateur de signaux d'attaque de commutateur bidirectionnel, et un circuit d'attaque de commutateur bidirectionnel.
