Abstract
In a switched-mode regulator for operation of an electromagnet having a magnet coil using different supply voltages the operating voltage UB of the electromagnet is produced by means of a storage circuit including a storage choke (2). To achieve cost and space-saving operation of the electromagnet using different supply voltages UV, the storage choke also acts as the magnet coil of the electromagnet.
Claims10
A switched-mode regulator having a storage choke (2), a momentary-contact switch (3), an electromagnet which includes a magnet coil, and an electronic control means (9) for operating this electromagnet having the magnet coil at a predetermined constant controlled operating voltage (UB) using different supply voltages (UV), said operating voltage being produced using said storage choke (2) connecting to a supply voltage in a storage circuit (1), said storage circuit having associated with it a sensor (7) connected to said electronic control means (9) which in turn controls the momentary-contact switch (3), wherein the storage choke (2) of said switched-mode regulator includes the magnet coil that also operates as the magnet coil of the electromagnet.
