CONTROL CIRCUIT FOR AN ELECTROMAGNET

摘要

The circuit includes a high voltage converter (10) with a main energy storage element (11) on which is stored a voltage higher than the supply voltage. A switch element (43) connects this main storage element to the electromagnet (40) and to an inductor (61) by way of which energy is transferred to a secondary energy storage element (64) which is used at the end of the electromagnet energisation period to cause rapid collapse of the electromagnet flux.
