WebbThis process of converting both half cycles of the input supply (alternating current) to direct current (DC) is termed full-wave rectification. The full-wave rectifier can be constructed in 2 ways. The first method makes use of a centre tapped transformer and 2 diodes. This arrangement is known as Center Tapped Full-Wave Rectifier.
