Electronic circuit for actuating an electromagnetic linear actuator

Abstract: an electronic circuit for actuating an electromagnetic linear actuator includes a ground input for a dc voltage source, a ground output to the electromagnetic linear actuator, a supply input for connecting the dc voltage source, a load output to the electromagnetic linear actuator, a first switch for selectively disconnecting the load output from the supply input, a second switch for selectively disconnecting the ground output from the ground input, and a control unit for controlling the first switch and the second switch. the load output is connected to the ground input by a first electronic valve and the ground output to an input side of the first switch by a second electronic valve, which each provide electrical connections in order to conduct an induction current induced in the electromagnetic linear actuator after opening of the electronically controllable switches.
