Title (DE) SCHALTUNGSANORDNUNG ZUM IMPULSBETRIEB VON HOCHDRUCKENTLADUNGSLAMPEN
(EN) ELECTRICAL CIRCUIT FOR THE PULSED OPERATION OF HIGH-PRESSURE GAS-DISCHARGE LAMPS
(FR) CIRCUIT DE FONCTIONNEMENT IMPULSIONNEL DE LAMPES A DECHARGE HAUTE PRESSION
Abstract:
(DE) Bei der Schaltungsanordnung zum Impulsbetrieb einer Hochdruckentladungslampe liegt die Lampe in Reihe mit Blindwiderständen. Zur Erzeugung der Tastimpulse sind parallel zu mindestens einem der in Reihe zur Lampe (La) liegenden Blindwiderstände (CI, LI) ein oder mehrere Blind widerstände (C3) als Energiespeicher in Reihe mit einem oder mehreren Schaltelementen (S3) angeordnet.
(EN) In the circuit proposed, the lamp is connected up in series with reactive impedances. In order to generate pulses, one or more reactive impedances (C3) is connected as the energy supply in series with one or more switch elements (S3) and in parallel with at least one of the reactive impedances (C1, L1) in series with the lamp (La).
(FR) Dans un circuit pour le fonctionnement impulsionnel d'une lampe à décharge haute pression, la lampe est mise en série avec des réactances. Pour la génération des impulsions de déclenchement sont disposées, parallèlement à au moins une des réactances (C1, L1) montées en série avec la lampe (La), une ou plusieurs réactances (C3) comme accumulateurs d'énergie en série avec un ou plusieurs éléments de circuit.
