Like half-wave rectifiers, they are cheap and have a smaller form factor than full-wave rectifiers.īridge rectifiers use four diodes to rectify the AC input signal. Like full-wave rectifiers, they are much more efficient than half-wave rectifiers and produce a higher quality output.

The rectifier is supplied an AC voltage from a step-down transformer.īridge rectifiers are designed to combine the best attributes of both half-wave and full wave rectifiers. Type Number of Diodes Transformer Type Output Half-Wave Rectifier 1 Normal Half-wave Full-Wave Rectifier 2 Center Tapped Full-wave Bridge Rectifier 4 Normal Full-waveīridge Rectifier A bridge rectifier consists of four diodes that rectify the AC input into a pulsed DC output.

The following table provides a comparison of each type of rectifier. The tradeoff is that bridge rectifiers require four diodes in a slightly more complex configuration in order to function. In contrast, half-wave rectifiers allow only one half (the positive half) of an AC waveform to pass and full-wave rectifiers require more expensive center tapped transformers to function. A bridge rectifier is a circuit that allows a complete alternating current (AC) waveform to pass, but uses a standard transformer thus keeping the cost low. Rectifiers are incredibly useful in the field of electronics because most electronic devices use DC, but the power grid (mains electricity) supplies AC.īridge rectifiers are the most commonly used type of rectifier because they combine the benefits of a full-wave rectifier while being only slightly more expensive than a half-wave rectifier. Rectifiers are circuits that turn an alternating current (AC) into a direct current (DC).
