A multiphase DC voltage converter and a method for controlling a multiphase DC voltage converter, having at least two parallel coils which are controlled in a time-shifted manner, at least one control unit for activating the coils, and at least one magnetically sensitive sensor element for detecting a magnetic field generated by the current flow through the coils. The control unit controls the current flow through the coils as a function of an output signal of the at least one sensor element.

A method and a circuit system for operating an electric machine are presented. The method is carried out in particular in a starting phase, a current being limited using a controllable resistor, the controllable resistor being implemented by at least one semiconductor switch, which is controlled using a clocked signal, and the signal being set in such a way that in shutdown phases, the at least one semiconductor switch is not completely shut down.

An integrated circuit for information transfer, having a substrate, at least one Hall element which is integrated into the substrate or situated on the substrate, a first coil which is situated essentially concentrically with respect to the Hall element and at a distance from the Hall element in the vertical direction and galvanically separated therefrom, and at least one second coil which is situated essentially concentrically with respect to the Hall element and galvanically separated therefrom and situated at a distance from the Hall element and the first coil in the vertical direction. The first coil and the second coil are electrically connected in series so that a current flow in the same direction results in the coils.

摘要:
A method for transmitting logical information from a transmitter to a receiver via a single line, the receiver being connected to the transmitter by the line, the receiver placing a first signal on the line and the first signal being made up of alternating recessive and dominant levels, the transmitter placing a second signal on the line and the second signal being superposed on the line by the transmitter at least in the segments in which the first signal has a recessive level, the second signal being made up of a sequence of recessive and dominant levels, and the receiver determining from the second signal the logical information that is to be received.

摘要:
A method for maintaining a predetermined voltage in a battery-supported vehicle electrical system during the operation of an electrical starter includes steps of operating the electrical starter on the vehicle electrical system during a first time phase in series with a limiting resistor, in order to limit the current flowing through the starter, and operating the electrical starter on the vehicle electrical system during a second time phase with a reduced limiting resistance, in order to increase a power converted by the starter. A transition from the first time phase to the second time phase is controlled on the basis of electrical parameters sampled during the first time phase at the limiting resistor.

In a method for operating a starter of a vehicle, a physical variable is measured, and a starter current of the starter is limited or not limited as a function of the measured physical variable, the limiting action being terminated after a predetermined period of time in the event that the starter current is limited.
