A method for laterally stabilizing a single-tracked motor vehicle, driven with the aid of an electric motor, that is in a vertically aligned state and at a standstill. The front wheel of the motor vehicle has a steering angle in which the electric motor is controlled in such a way that it exerts drive torques on the motor vehicle that act in alternation in the forward direction and in the reverse direction.

Method and device for lateral stabilization for a single-tracked motor vehicle at a standstill

The invention relates to a drive system, in particular for a vehicle, comprising a fuel cell unit for generating electric energy, a secondary battery for storing electric energy, an electric machine with windings, and an inverter for actuating the electric machine. The inverter is designed as a 3-level inverter and has multiple electronic switches, diodes, a plus pole, a minus pole, and a neutral pole. The fuel cell unit and the secondary battery are connected in series and are connected to the poles of the inverter. The invention also relates to a method for heating a drive system according to the invention, wherein the switches of the inverter are actuated such that a short-circuit current path is produced between the poles of the inverter to which the fuel cell unit is connected.

Drive system, in particular for a vehicle, and method for heating a drive system

A circuit configuration for supplying the control electronics in an electrical machine is specified, which includes a passive transformer circuit, which is powered by a phase current IP of the electrical machine and which generates an auxiliary voltage VA that is used for supplying the output stage of the electrical machine if no battery is present or if the battery is defective or discharged.

Circuit arrangement for supplying a control electronics system in electric machines

A three-phase generator that has a plurality of stator windings, a rectifier system connected with the stator windings, an exciter winding, a generator controller, and an additional circuit that effects an increase in voltage. This additional circuit is a passively operated booster circuit that is integrated into the generator and that has no controlled components.

Three-phase generator having increased output

A circuit arrangement for an electrical machine which is connected with at least one phase terminal of the electrical machine, has at least one passive charge pump connectable directly with phase windings of the electrical machine and having another terminal connected through further electronic means with an input/output, at which a switching on/switching off signal for a current supply is produced.

Circuit arrangement for electrical machines

The electrical machine, especially a three-phase generator, has a stationary stator ( ); a rotatable rotor having an excitation coil ( ), a rotary transformer ( ) having a primary winding ( ) and a secondary winding ( ) on respective soft ferrite cores and magnetically coupled with each other via an air gap ( ) and a control circuit ( ) for loading the primary winding ( ) of the rotary transformer ( ) with an alternating current. The control circuit ( ) includes an input-side current limiting circuit ( ), whereby an integrated temperature control is obtained in cooperation with the soft ferrite cores of the primary and secondary windings according to the Curie effect.
