  • Control circuit for an actuator
    Patent number: 7415971
    Abstract: In a control circuit for at least one actuator, in particular for a capacitive actuator of an injection system of an internal combustion engine, a control current can be applied to the actuator. The control circuit has an inductor, e.g., having a core and having multiple windings, the windings being designed and connected to the control circuit such that a control current flowing into the actuator and a control current flowing out of the actuator each flow through different windings of the inductor, and a magnetic flux induced in the inductor or its core by the control current flowing into the actuator and a magnetic flux induced in the inductor or its core by the control current flowing out of the actuator mutually compensate one another.
