Abstract

Es wird eine Schaltungsvorrichtung zur Regelung eines durch eine Magnetspulenanordnung (14) fließenden Spulenstromes (IS) vorgeschlagen, mit einer Regeleinrichtung (26), die eine Meßanordnung (16, 21) zum Messen des Spulenstromes (IS) aufweist und die den Spulenstrom (IS) in Abhängigkeit von der gemessenen Spulenstromstärke regelt, mit Mitteln zur Erzeugung eines durch die Magnetspulenanordnung (14) fließenden, durch Taktung geregelten Anzugsstromes (IA) und mit einer Umschalteinrichtung (25) zur Absenkung des Spulenstromes (IS) nach Ablauf einer Anzugszeitdauer (TA) auf einen geringeren, bis zum Ende eines Schaltsignales (UG bzw. UO) fließenden, getakteten Haltestrom (IH). Die Meßanordnung (16, 21) ist außerhalb des Freilaufstromkreises (18) geschaltet, in dem während des in den Taktpausen vorliegenden Freilaufzustands der Magnetspulenanordnung (14) der Freilaufstrom fließt. Hierdurch muß die Eingangsspannung nicht an den gewünschten Anzugsstrom angepaßt sein, und der Freilaufstrom erzeugt in der Meßanordnung keine Verlustleistung.

Figure 00000001
A circuit device for regulating a coil current (IS) flowing through a magnet coil arrangement (14) is proposed, with a control device (26) which has a measuring arrangement (16, 21) for measuring the coil current (IS) and which detects the coil current (IS). as a function of the measured coil current strength, with means for generating a starting current (IA) flowing through the magnet coil arrangement (14) and regulated by clocking, and with a switching device (25) for lowering the coil current (IS) after a starting period (TA) has elapsed a lower, clocked holding current (IH) flowing until the end of a switching signal (UG or UO). The measuring arrangement (16, 21) is connected outside the freewheeling circuit (18), in which the freewheeling current flows during the freewheeling state of the magnet coil arrangement (14) during the cycle breaks. As a result, the input voltage does not have to be adapted to the desired starting current, and the freewheeling current does not generate any power loss in the measuring arrangement.
