Abstract
A control circuit for an electromagnet includes a high voltage converter with a main energy storage element on which is stored a voltage higher than the supply voltage. A switch element connects this main storage element to the electromagnet and to an inductor by way of which energy is transferred to a secondary energy storage element which is used at the end of the electromagnet energization period to cause rapid collapse of the electromagnet flux.
