  • Voltage regulator for magnetogenerators with configurable connection of the phase windings
    Patent number: 7948218
    Abstract: The voltage regulator receives power in A.C. from a permanent magnet voltage generator, having phase windings with a configurable connection, to supply power in D.C. to a battery. The voltage regulator comprises a plurality of semi-bridge rectifiers connected between the terminals of the phase windings of the voltage generator, and a battery power supply terminal; it also comprises a control circuit designed to change over the connection of the phase windings between two different configurations, for example star and delta, in relation to the charging voltage of the battery upon exceeding a threshold value of the phase frequency of the voltage generator.
