Abstract
Disclosed are a method and an arrangement for controlling the output voltage of a generator arrangement.
Claims23
A method for controlling an output voltage of a generator arrangement that comprises a generator having a field winding, the method comprising:
- generating a controlled field current for the field winding dependent on the output voltage and dependent on at least one control parameter that is dependent on a rotational speed of the generator.
A circuit arrangement for controlling an output voltage of a generator arrangement, the generator arrangement having a generator with a field winding, the circuit arrangement comprising:
- a first input for receiving an output voltage signal that is dependent on the output voltage;
- a second input for receiving a rotational speed signal that is dependent on a rotational speed of the generator;
- wherein the circuit arrangement includes circuitry that is adapted to generate a controlled field current for the field winding, the field current being dependent on the output voltage and being dependent on at least one control parameter that is dependent on the rotational speed of the generator.
A voltage supply arrangement, comprising:
- a generator arrangement having a generator that comprises a field winding, and output terminals for providing an output voltage;
- a rotational speed detection unit that is adapted to detect a rotational speed of the generator and to generate a rotational speed signal being dependent on the rotational speed;
- and
- a circuit arrangement for generating a field current for the field winding, the circuit arrangement receiving an output voltage signal that is dependent on the output voltage and the rotational speed signal and that is adapted to generate a controlled field current for the field winding, the field current being dependent on the output voltage and being dependent on at least one control parameter that is dependent on the rotational speed of the generator.
