Voltage regulator for magnetogenerators protected against erroneous connections

The series-type single-phase voltage regulator, for voltage generators, comprises a semicontrolled bridge rectifier (D2, D7, Q1, Q4), in which a first and a second branch of the bridge comprise a controlled power diode or SCR (Q1; Q4) connected between a respective terminal (G1, G2) of the magnetogenerator, and a positive terminal (B) of a battery (BA). The control electrode of the SCR diode (Q1; Q4) is connected to a switching ON-OFF circuit comprising a controlled switch (Q3; Q7) provided by an SCR which can only be switched on by the voltage of the battery (BA). Two controlled SCR switches (Q2; Q5) are connected in anti-parallel to the terminals (G1, G2) of the magnetogenerator.
