Patent ID: 7211988

Claim:
A device for producing electrical power, comprising: a rotational energy source to be rotated at a rotational speed, a generator having a generator rotor to be driven by the rotational energy source, the generator rotor further comprising a specific geometry, and having a stator assembly with a geometry which is matched to the geometry of the generator rotor, the stator having windings through which an electrical generator currents are flowing, said geometries being selected such that they provide both local magnetic saturation effects and specific field-distortion effects in order to produce a constant generator current by a feedback control system, which is independent of the rotational speed, a rectifier rectifying the generator so as to provide an intermediate DC voltage, said feedback control system connected to the generator and receiving the intermediate DC voltage, which control system controls the magnetic field induced in the generator in accordance with generator parameters such that an essentially constant current level is output by said generator, independently of the energy introduced into the generator and independently of the energy drawn off from the power producing device, wherein the control system comprises two switching elements connected in series across the intermediate DC voltage and two capacitors connected in series across an output voltage, wherein a node between the two switching elements and a node between the two capacitors are connected with each other, and wherein the two switching elements can be actuated and closed separately from each other.
