    Abstract: A step-down circuit is connected to an output of a step-up circuit that steps up a battery voltage, and an output of the step-down circuit is connected to a power supply input terminal of a CPU via an FET. The step-down circuit is normally maintained in an inactive state and, in response to an ignition switch being turned off, the CPU causes the step-down circuit to actuate and a stepped-down voltage (equal to a stabilized voltage) is output from the step-down circuit. The stepped-down voltage is further stepped down to a CPU power supply voltage, and the CPU power supply voltage is supplied to the power supply input terminal of the CPU. This allows the residual charge of the step-up circuit to be dissipated by the step-down circuit and the CPU.

    Abstract: A circuit configuration for inductively heating at least one fuel injection valve includes a power-transistor full-bridge circuit which acts as a driver for operating a series resonant circuit at an alternating voltage at or near the resonant frequency. The series resonant circuit includes a heater coil on which the resulting voltage can be significantly higher than the supply voltage. The power that can be fed to the heater coil can be modified or controlled by changing the frequency or the duty factor of the control signals of the switching elements of the bridge circuit. A fuel injection valve and methods for operating the circuit configuration are also provided.

    Abstract: A control device actuates at least one fuel injection valve with a high voltage and a comparatively lower voltage in temporally consecutive phases. The control device has supply connections for supplying energy from a motor vehicle battery. One of the connections is connected to vehicle ground. First output connections provide a positive first output voltage with respect to vehicle ground, the voltage being smaller than or equal to a hazard voltage of 60 volts of direct current according to TRBS2131. Second output connections provide a positive second output voltage with respect to vehicle ground, the voltage being greater than the hazard voltage and smaller than a sum of the first output voltage and the hazard voltage. The positive potentials of the first and second output voltages (U1, U2) are linked together.

    Abstract: A method actuates a fuel injector having a coil drive with a solenoid and a magnet armature. The magnet armature can be moved along a longitudinal axis by a magnetic field generated by the solenoid. In the method, an amplification voltage is applied to the solenoid at a predefined point in time to move the magnet armature from a closed position into an open position. The amplification voltage is made available by a voltage-regulated direct voltage transformer from a supply voltage. The direct voltage transformer has a storage capacitor for supporting the voltage made available at the output of the direct voltage transformer. The storage capacitor is charged to a pilot control voltage by the amplification voltage before the given point in time, with the result that the voltage present at the solenoid is higher than the amplification voltage at the predefined point in time.
