Control of the attraction of an armature of a switching magnet and a switching arrangement for performing the method
First Claim
1. A method of regulation of the attraction of an armature of an electromagnet for operation of a control element, said method comprising providing at least one supply voltage, regulating the at least one supply voltage to provide a regulated supply voltage as an intermediate voltage value, and utilizing the regulated supply voltage in a current regulator to supply a regulated supply current of a desired value to the coil of the electromagnet;
- and wherein the step of regulating the at least one supply voltage to provide a regulated supply voltage includes regulating the at least one supply voltage, under control of a feedback signal from the current regulator, to the lowest supply voltage value sufficient to regulate the current to a desired value in order to build up the magnetic field of the electromagnet, whereby energy-saving regulation of the current is achieved.

Abstract
A method of energy-saving regulation of the attraction of an armature of a switching magnet, particularly an electromagnet for a control element in an internal combustion engine, wherein a medium voltage UZ is formed by switching to the lowest-available supply voltage UV, the medium voltage being sufficient to regulate a current IS in order to build up the magnetic field of the electromagnet.
