Title
(EN) MAGNETRON CONTROLLER WITH TRANSFORMER CONTROLLING THE INRUSH CURRENT
(FR) UNITE DE COMMANDE DE MAGNETRON A TRANSFORMATEUR AGISSANT SUR L'APPEL DE COURANT
Abstract
(EN)
A control unit for a magnetron (1), the circuit being supplied from a source of a.c. voltage and comprising a power switch, a process controller/firing circuit for the power switch and first (7) and second (9) transformers. The first transformer supplies a desired filament voltage to the magnetron and the second transformer controls the current flow in the magnetron and hence the power output. The second transformer is controlled by the operation of the process controller/firing circuit and the power switch to provide an infinitely variable power output setting to the magnetron.
(FR)
Cette invention a trait à une unité de commande de magnétron (1). Le circuit est alimenté par une source de tension de courant alternatif et est pourvu d'un commutateur, d'une commande de processus/circuit d'allumage du commutateur et de deux transformateurs (7, 9). Le premier transformateur fournit au magnétron une tension désirée appliquée au filament et le second commande la circulation de courant dans le magnétron et, de ce fait, la puissance de sortie. Le second transformateur est commandé par la commande de processus/le circuit d'allumage et par le commutateur pour assurer une puissance de sortie infiniment variable au magnétron.
