Abstract

Eine Ansteuereinrichtung für eine Magnetspule weist eine Ansteuerschaltung auf, die sowohl den Augenblickswert der Spannung, mit der die Spule beaufschlagt wird, als auch den Augenblickswert des Spulenladestroms überwacht. A control device for a solenoid coil has a control circuit which monitors both the instantaneous value of the voltage with which the coil is applied, and the instantaneous value of the coil charging current. Erreicht dieser einen Schwellwert wird eine Zeitschaltung (15) gestartet, deren Zeitverzögerung von der anliegenden Spannung (U N ) beeinflusst wird. Reaches a threshold value that is started, the time delay (U N) is influenced by the applied voltage, a timing circuit (15). Je größer die Spannung ist desto geringer ist die Zeitverzögerung der Zeitschaltung (15). The higher the voltage, the lower is the time delay of the timing circuit (15). Die Steuerschaltung (4) schaltet den Spulenladestrom ab sobald die von der Zeitschaltung vorgegebene Verzögerungszeit abgelaufen ist. The control circuit (4) switches the coil charging current off as soon as the predetermined time of the circuit delay time has expired. Der Spulenstrom kommutiert nun auf eine Freilaufdiode. The inductor current flows now a free-wheeling diode. Die Steuerschaltung (4) schaltet den Spulenladestrom über den Transistor (T) erst in der Nähe des Nulldurchgangs der Versorgungsspannung überein. The control circuit (4) switches match the coil charging current through the transistor (T) only in the vicinity of the zero crossing of the supply voltage. Durch geeignete Abstimmung der Abhängigkeit der Zeitverzögerung von der Versorgungsspannung lässt sich erreichen, dass die Magnetspule in äußerst weiten Grenzen der Versorgungsspannung mit einem immer gleichen Strom, insbesondere mit einem konstanten Effektivwert beaufschlagt wird. By appropriate adjustment of the function of the time delay of the supply voltage that the magnetic coil is applied in a very wide range of supply voltage with an identical stream, especially with a constant effective value can be achieved.
