Advantages and Drawbacks of Bridge Rectifiersīridge rectifiers are so common because they combine the main advantages of both half-wave and full-wave rectifiers. This results in a waveform that much more closely resembles an ideal DC signal, which would be a flat line. The solid line represents the improved waveform due to the inclusion of a capacitor. The dashed curve represents the output of the rectifier without a capacitor. The output of a bridge rectifier with a smoothing capacitor filter. Current in the diode can only flow from the anode to the cathode: Diodes only allow electric current to flow in only one direction, based on the operation of semiconductor p-n junctions. Like half-wave and full-wave rectifiers, bridge rectifiers rely on the functionality of diodes. This is a significant improvement over the output of an HWR, whose waveform features pulses separated by equal periods where the voltage equals zero (0). The result is an output waveform that is identical to the output of a full-wave rectifier and features continuous pulses. In a bridge rectifier, two diodes are used to rectify the positive part of the AC waveform, and two diodes are used to rectify the negative part of the AC waveform. Therefore the diode bridge configuration is a way of taking advantage of the inherent properties of the transformer and diodes.

This means that the load sees a sequence of positive pulses rather than an alternating current. The whole idea of the diode bridge is that current always flows through the load in the same direction. The term ‘bridge’ refers to a specific configuration of four diodes, which is also called a diode bridge or Graetz circuit. 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). Lesson 3: Bridge Rectifier Bridge Rectifier Lesson 0: Introduction to Analog Circuits
