Abstract

Die Erfindung bezieht sich auf den Leistungsteil einer Schaltung zur Steuerung eines bistabilen magnetischen Aktuators. Um eine verkürzte Thyristor-Freiwerdezeit zur Freigabe der entgegengesetzt gerichteten Schaltbewegung zu erzielen, wird eine Schaltung vorgeschlagen, bei der die jeweils nicht aktive Wicklung (L1, L2) des Aktuators während der Freilaufphase nicht stromdurchflossen ist, so daß keine Gegen-EMK erzeugt werden kann. Bei einer zweiten Schaltungsvariante wird durch Anordnung zweier Freilaufdioden (D1, D2) und zweier Entladeschalter (S01, S02) eine Rückspeisung des Freilaufstromes zu einem Energiespeicher (E) ermöglicht.

The invention relates to the power section of a circuit for controlling a bistable magnetic actuator. In order to achieve a shortened thyristor release time for releasing the oppositely directed switching movement, a circuit is proposed in which the respectively inactive winding (L 1 , L 2 ) of the actuator does not have current flowing through it during the freewheeling phase, so that no back emf is generated can be. In a second circuit variant, the arrangement of two freewheeling diodes (D 1 , D 2 ) and two discharge switches (S 01 , S 02 ) enables the freewheeling current to be fed back to an energy store (E).
