Design (2005-2011): Rectifier
Alternating current (AC) is created in the generator stator windings. This must be converted to direct current (DC) before it can be used in the electrical system of the car.
This conversion is made using a rectifier bridge which consists of six diodes, two diodes per phase winding.
Alternator 150 A with its double stator windings has twice the number of diodes, that is, 12 diodes. The diodes are pressed into a diode holder.
