Generator (Gen) (2005-2007): Design: 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.
The stator windings generate three phases and are delta connected An exciter diode is connected to each of the three stator windings. The six rectifier diodes are bridge connected. The diodes are pressed into a diode holder.
