Abstract: An electronic apparatus for a rotating electric machine, notably an alternator voltage regulator or speed variator, including an electronic circuit and a wired bus allowing the exchange of information with the outside, such that the bus is defined by an interface module rigidly fixed to a board of the electronic circuit and communicating via a wireless link with the latter.

Abstract: The invention relates to a system for generating electric power, comprising: an alternator (1) for coupling with a drive system (7), supplying an AC voltage to an output bus (10); a reversible AC/DC converter (2) in which the AC bus (6) is connected to the output bus (10) of the alternator (1); an electricity-storage element (3) connected to the DC bus (9) of the converter (2); a controller (4) arranged to react to a transient state of load-shedding or charging impact by controlling the converter (2) so as to collect energy on the output bus (10) of the alternator (2) and to store same in the storage element (3) in the case of load-shedding, and to collect energy in the storage element (3) and to inject same into the output bus (10) in the case of charging impact, the converter (2) being controlled so as to inject currents to compensate for harmonic currents into the AC bus (10) of the alternator (1).

Abstract: A system for controlling and regulating a generating set including an alternator that is mechanically coupled to a drive motor, the alternator including a terminal box borne by a casing and containing electric connections connected to the windings of the alternator. The system includes a controller part for controlling the motor of the generating set and a regulator part for regulating an output voltage of the alternator, the voltage regulator part being positioned outside the terminal box and solidly connected to the controller part of the set.

Abstract: The present invention relates to an alternator to be electrically connected to a load, the alternator including a rotor including: a rotary field, an excitation winding, a dissipative component and a switchover system allowing the rotary field to be connected selectively to the excitation winding or to the dissipative component, and a controller controlling the switchover system so as to regulate the current in the rotary field and, in response to a reduction in the load applied to the alternator, connects the dissipative component to the rotary field to dissipate the inductive energy that has built up in the rotary field.
