Abstract (en)
[origin: CN102647139A] The present invention provides a synchronous alternator comprising a coil wound rotor and an ASSEMBLY OPERATING a converter VARIABLE REGIME especially with a variable speed, power or power factor, comprising: a synchronous alternator (10) comprising a rotor coil (15) supplied with DC current via a voltage (Vf), especially by means of a dynamo (11) or direct generation via rings and collectors, and delivering an output voltage (US); and a converter (20) comprising a rectifier (21) for rectifying the voltage (US) of the alternator, the rectifier possibly being a pulse-width modulation rectifier or a diode-comprising rectifier and optionally followed by a DC/DC converter, the supply voltage (Vf) of the rotor coil being controlled by the output voltage (US) of the alternator.
