Rectifier Assembly
The Rectifier Assembly consists of six diodes, a pair of diodes for each stator winding.
Each pair contain one positive biased diode and one negative biased diode. By using a pair of diodes that are reversed biased to each other, rectification of both sides of the AC sine wave is achieved. The negative biased diodes allow for conducting current from the negative side of the AC sine wave and putting this current into the circuit as positive current.
The use of positive and negative biased diodes provide for full wave rectification because both halves of the sine wave are used.
