ASSEMBLY OPERATING IN VARIABLE SITUATION

摘要

PROBLEM TO BE SOLVED: To provide an electromechanical assembly operating in a variable situation, especially having variable speed, power or power factor.SOLUTION: The invention includes: a synchronous alternator (10) having a rotor coil (15), supplied with DC current through voltage (V) especially using a dynamo (11) or by direct power generation by a ring and a collector, and delivering output voltage (US); and a converter 20 having a rectifier (21) for rectifying the voltage US of the alternator, optionally including a pulse width modulated rectifier or diode and optionally followed by a DC/DC converter. The supply voltage (V) powering the rotor coil is controlled by the output voltage (US) of the alternator.SELECTED DRAWING: Figure 1
