Abstract
An electronic circuit configured to control an electromagnetic actuator with an electric coil, comprising at least one first electronic switching element, a capacitor, and a diode connected to the first electronic switching element, the capacitor, and the electrical coil to form a step-up converter, wherein the capacitor is configured to be charged to a voltage that is greater than an operating voltage of the electronic circuit.
Claims20
A method for improving measurability of an end time of a mechanical switch-on operation of an electromagnetic actuator having an iron core displaceable in the electromagnetic actuator by energizing an electrical coil configured to act on a coil voltage via an electronic control circuit in order to energize the coil by utilizing a coil current, the method comprising:
- supplying the electronic control circuit with an operating voltage;
- charging a capacitor situated in the electronic control circuit;
- and
- discharging the capacitor in order to increase the coil voltage during the mechanical switch-on operation to a value greater than the operating voltage.
