Abstract
A circuit arrangement and also a method for controlling a bistable magnetic valve in which a magnetic valve is to be supplied with a pulse of electrical current in order to switch over the magnetic valve from a first stable state into a second stable state, comprises a power supply source to provide a supply voltage, a power supply device fed by the power supply source and able to be activated for the duration of the current pulse by an entered control signal (Enable) to create a coil current (I) flowing through the magnetic coil, with the coil current (I) being set to a setpoint, where changeover means are provided in order to reduce the setpoint of the coil current during the current pulse. This advantageously allows the power dissipation of the activation of bistable magnetic valves to be reduced.
