  • Patent number: 11233399
    Abstract: Method for regulating a bank of alternators comprising at least two alternators that deliver their output in parallel to a load (C), said alternators each being provided with a regulator (12, 13) that is configured to deliver an output signal representative of the reactive power level of the corresponding alternator divided by its nominal reactive power, and a control law allowing the reactive power level of the alternator to be modified depending on an input signal, method wherein a weighted signal employed as the input signal of these regulators is generated from the output signals representative of the reactive power level of each of the alternators, i.e. the signals delivered by the corresponding regulators, so as to make each of the alternators converge to a predefined reactive power level (Trp).

  • Patent number: 11171590
    Abstract: An electronic device, in particular an alternator regulator, comprising a power stage to be connected to an inductive load, in particular to an alternator inductor, comprising at least one first pair of power transistors connected to a terminal of a DC bus, and a control circuit for said transistors, the transistors being disposed in parallel between said terminal of the DC bus and a first output to be connected to the load, at least one flyback diode connecting the opposite terminal of the DC bus to the first output, the control circuit being designed to generate a pulsed control signal for regulating the current in the load and for detecting a failure of one of the transistors, the control circuit being designed, during normal operation, to send the control signal to one of the transistors of the first pair, while maintaining the other transistor of said pair in an off-state.

  • Patent number: 11050374
    Abstract: A method for customizing operation of an alternator regulator including at least one processor executing a program governing its operation. The regulator receives input signals and acts on output signals according to at least one control law. The control law is implemented in the regulator by a programming interface by inputting at least coordinates (x, f(x)) of at least two points of the law.

  • Publication number: 20200053906
    Abstract: An electronic device, in particular a variable speed drive or alternator regulator, comprising a heat sink (10) and a power card comprising a printed circuit board, housed in a casing, characterized in that it comprises a part (100) attached, on the one hand, to the heat sink (10) and attached, on the other hand, to the board and coming into contact with at least one conductive track of the power card, so as to provide an electrical contact between the heat sink and said track, said part (100) having a face that is accessible from the outside of the device for attaching a lug connected to a ground and/or an earth cable.
