CA 2088252

In known line-powered, phase control circuits, the middle point (b) of a serial connection between an inductance (1a) and a switch (T1) connected to the output (a) of the power line rectifier (BG) is connected by an inductance (D1) to a charging capacitor (Cb). The object of the invention is to reduce in such circuits the amplitude of the harmonic waves drawn from the power line. For that purpose; a second diode (D2) is arranged between the middle point (b) and the switch (T1), and the switch (T1) is connected by the primary winding (Lp) of a combinatorial circuit transformer (Tr) to the charging capacitor (Cb). The invention is particularly useful for television receivers or video-recorders.

Dans des circuits connus de commande par coupe fonctionnant sur secteur, le point central (b) d'une interconnexion en série d'une inductance (La) et d'un commutateur (T1) raccordés à la sortie (a) du redresseur de secteur (BG) est raccordé par une inductance (D1) à un condensateur de charge (Cb). Le but de l'invention est de réduire, dans un tel circuit, l'amplitude des harmoniques tirées du secteur. A cet effet, une deuxième diode (D2) est montée entre le point central (b) et le commutateur (T1), le commutateur (T1) étant connecté au condensateur de charge (Cb) par l'enroulement primaire (Lp) d'un transformateur (Tr) de la partie de réseau combinatoire. L'invention est particulièrement utile dans des postes récepteurs de télévision ou dans des magnétoscopes.
