Abstract:
1. A voltage regulator suitable to change an A.C. power of a voltage magnetogenerator, into a D.C. power supplied to a battery, in which the voltage magnetogenerator comprises a rotor and a plurality of phase windings each having first and second connecting terminals, and in which the voltage regulator is conformed for changing the connection of the phase windings between a first and a second configuration in relation to a rated voltage of the battery and a voltage frequency of the magnetogenerator; comprising: first and second semi-bridge rectifiers connected, in phase opposition with one another, between a corresponding terminal of a respective phase winding of the magnetogenerator, and the battery; a winding configuration control circuit for changing the connection of the phase windings, the winding configuration circuit comprising a plurality of switching devices, each consisting of first and second electronic switches connected in anti-parallel, in a looped circuit, in which the connection point between two adjacent switching devices is in turn connected to one terminal of a respective phase winding; a pilot circuit for the winding configuration circuit, the pilot circuit being connected to control electrodes of said first and second electronic switches of the switching devices respectively being operatively connected to a voltage measuring circuit for the battery, and to a phase-frequency detecting circuit; the phase frequency detecting circuit being conformed to activate the pilot circuit and to selectively change the connection configuration of the windings at a pre-established threshold value of the voltage frequency detected by said frequency detecting circuit.
