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.

Electronic device, in particular an alternator regulator, and method for regulating such a device

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.
