Abstract
The voltage-regulator circuit includes: PA0 a driver transistor whose collector-emitter path is in series with the field winding between two poles of a source of a direct-current voltage, and PA0 a control circuit adapted to drive the transistor in an on-off manner in dependence on the value assumed by the voltage supplied by the generator in comparison with a reference voltage and in dependence on the field current detected by a resistor connected to the transistor.
