Abstract
A device for producing electricity, the device comprising a three-phase alternator comprising three windings, a rectifier for converting the AC delivered by the alternator into rectified current, and a voltage-raising chopper using the self-inductance of the alternator to raise the voltage. The device includes a switch unit enabling the three windings to be connected either in a star configuration when the alternator is being rotated to produce electricity, or else to the respective phases of a three-phase network when the alternator is stopped.
Claims10
A device for producing electricity and comprising:
- a three-phase alternator having no motor function, comprising three windings, said alternator having a self-inductance;
- a rectifier for converting the alternating current delivered by the alternator into rectified current;
- a voltage-raising chopper having at least one switch element enabling a higher voltage to be generated across the terminals of the alternator due to the self-inductance of the alternator;
- and
- a switch unit enabling the three windings to be connected either in a star configuration when the alternator is being rotated to produce electricity, or else to connect the three windings to respective phases of a three-phase network when the alternator is stopped.
