Abstract (en)

[origin: WO9015922A1] The invention relates to a circuit for operating electromagnetic users, especially magnetic valves in internal combustion engines. To ensure the lowest possible losses, it is proposed to provide at least two mutually independent controllable connecting devices (4, 5) which apply different voltages (U1?, U2?) to the user (1).
