  • Publication number: 20210083481
    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).

  • Publication number: 20200053907
    Abstract: An assembly comprising: an electronic device (1), in particular a variable speed drive or alternator regulator, comprising a casing, the rear of which is equipped with a heat sink (10), produced from a metal profile section, for cooling at least one power component; a first assembly of elements (20) for attaching the device on a support, each comprising at least one tab to be engaged in the profile section by sliding it therein, and an attachment lug provided with at least one screw through-hole; a second assembly of elements for attaching the device on a support, each comprising at least one tab to be engaged in the profile section by sliding it therein, and an attachment lug provided with at least one screw through-hole, the elements being of different shapes.

  • Publication number: 20200052630
    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.

  • Publication number: 20190173405
    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.
