ELECTROMAGNET CONTROLLER Russian patent published in 2009 - IPC H01F7/18 

FIELD: physics; electricity.

SUBSTANCE: invention aims at forced feed of switch electromagnet coil from DC and AC voltage source. Device ensures required forced making and confinement conditions at rated electromagnet gate voltage automatically maintaining these conditions with gate voltage multiplication. Operation of the controller is based on the invariant principle of pulse voltage stabilisation in the coil both in forced making and confinement conditions. Electromagnet controller contains transistor key, matching key element within control circuit, electromagnet coil shunting diode, timer, pulse generator, two switches, current-specifying circuit, two integrating capacitors and auxiliary power supply.

EFFECT: higher performance reliability within wide range of gate voltage and extended applications of device.
