Plant vehicle electrical systems can only use direct current electricity (DC).

Electrical generators used on plant vehicles and machines produce alternating current (AC).

Before this AC can be used, it must first be rectified by using diodes to convert the AC to DC.

Depending on the number of diodes we use, and how we use them, we can get full wave rectification or half wave rectification.

Full wave rectification makes use of all the electricity generated - the negative output is brought above the 0 Volts line by the action of the diodes.

Check out this course project which analyses full wave rectification and half wave rectification.
