Rectifier
The current produced by the generator's stator winding must be converted to direct current before it can be used in the car's electrical system. The current
is converted by means of 6 Zener diodes, 2 per phase winding.
Voltage regulator
The purpose of the voltage regulator is to maintain the voltage from the generator, whatever its speed and load-demand, at a constant level regardless of
engine speed.
If the load causes the voltage generated to exceed the rated reference value (approx. 14 V), the regulator will reduce or break the exciting current. The
generator's excitation decreases, lowering the voltage from the stator windings. When the voltage has dropped below the reference value (approx. 14 V),
excitation increases, as does the generator voltage, until the reference value is once again exceeded. This process is repeated continuously.
