A bridge rectifier is a highly efficient type of full-wave rectifier that can convert AC to DC without the need for a center-tapped transformer. By using a standard transformer and four diodes in a bridge configuration, it can rectify the full AC wave, making it a cost-effective solution for many applications. With its reliable performance and low cost, the bridge rectifier is a popular choice for many electronic circuits.
Full wave Rectifier
A full-wave rectifier is a circuit that allows a complete alternating current (AC) waveform to pass, turning an AC signal into a pulsed direct current (DC) signal.
Half wave Rectifier
half-wave rectifiers allow only one half (the positive half) of an AC waveform to pass. The negative part of the AC waveform is essentially wasted. By using the full AC input wave, a full-wave rectifier (FWR) is twice as efficient as a half-wave rectifier and produces a higher quality DC signal.
However a full-wave rectifier uses two diodes where a half-wave rectifier requires only one, and an FWR also requires a larger/more complex transformer known as a center tapped transformer.
