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.

The 150 A generator (GEN) has twin rectifier bridges due to its double stator windings, in other words it has 12 diodes. The diodes are pressed into a diode holder.
