The invention relates to a device () for inductively charging an electrical storage unit, in particular of a motor vehicle, comprising a stationary primary coil () and a secondary coil that is or can be associated with the motor vehicle, wherein at least one resonance capacitor () is associated with the primary coil () and the secondary coil, respectively. According to the invention, at least one of the resonance capacitors () is designed to at least substantially surround the coil () in question or to at least substantially be surrounded by the coil () in question.

Device for inductively charging an electrical storage unit

An output stage, especially a switching output stage for switching inductive loads, having a plurality of individual output stages that are connected in parallel, which include degenerative transistors, in the degenerative path of which one respective Zener diode is present. The electric power during a switching-off process can be distributed in a particularly uniform manner to the individual output stages or transistors by disposing the Zener diodes near the associated transistors so that they are thermally coupled to the respectively associated transistor and their Zener voltage increases with increasing temperature.

Output stage having zener voltage balancing

A method for operating an inductive load, which is operated in a motor vehicle with electric voltages of different magnitudes, is provided, a current rise in the inductive load being influenced by selecting pulse lengths and pulse pauses of the electric voltage.

Method and device for operating an inductive load with different electric voltages

A device and method for triggering an inductor having a trigger circuit and a first and second extinguishing device, the trigger circuit triggering a switch element, which establishes or interrupts a current flow to the inductor, the trigger circuit, in the interruption of the current flow to the inductor, initially operating the first extinguishing device, and, following a free-wheeling extinction time, which does not fall below a minimum time, operating the second extinguishing device, the first and second extinguishing devices extinguishing a current induced in the inductor, and the second extinguishing device extinguishing the induced current more rapidly than the first extinguishing device.

Device and method for triggering an inductor

A device and a method are described for controlling an electromagnetic user, especially a magnetic valve for influencing the fuel quantity to be injected into an internal combustion engine. At least one switching time of the user is taken into consideration in the control. The at least one switching time is ascertained starting from a current value.

Method and device for controlling an electromagnetic consumer

An arrangement for monitoring the drive of an actuator includes an output-stage component which includes a counter. With the aid of the counter, the switch-on time of the actuator is determined. The determined switch-on time is made available to the microcomputer for diagnostic purposes.

Method and arrangement for monitoring the drive of an actuator

A method and device for triggering a solenoid valve for injecting fuel into an internal combustion engine is described. The triggering phase of the solenoid valve is subdivided into a pull-up phase and a holding phase. During the pull-up phase, a valve needle of the solenoid valve is caused to open by a first current intensity flowing through a magnetic coil of the solenoid valve. During the holding phase, the valve needle is held in the open state by a second, lower current intensity flowing through the magnetic coil. At least once at the beginning of the pull-up phase, a booster phase is activated during which a pulse-shaped booster current from a booster capacitor charged to a high voltage flows through the magnetic coil. During the triggering phase of the solenoid valve, a plurality of booster pulses are activated in succession, whose time position within the triggering phase is freely selectable.

Method and device for triggering a fuel injector

A method and a device for driving at least one solenoid valve used for controlling the injection of fuel into an internal combustion engine. At the start of the driving (activation), the solenoid valve is supplied with a booster voltage that is elevated as compared to that used for the further driving. The energy and/or power output received by the solenoid valve at the start of the driving is able to be influenced as a function of the operating state of the internal combustion engine.
