  Bridge Rectifier
Bridge rectifier consists of four diodes connected in a bridge circuit that provides the output voltage of same polarity for any polarity of the input voltage.
Bridge rectifier is used for conversion of alternating current (AC) input into direct current (DC) output.
The four diodes in full wave rectifier are arranged in such a manner that both the positive and negative parts of the AC waveform are converted to DC.

Bridge Rectifiers Advantage The main benefit of bridge rectifiers over conventional full-wave rectifiers is that with a given transformer, the bridge rectifiers generate a voltage output that is nearly twice that of conventional full-wave circuit.
Another benefit of bridge rectifiers is the low ratio of peak inverse voltage to average output voltage.
A half-wave rectifier is a circuit that allows only one half-cycle of the AC voltage waveform to be applied to the load, resulting in one non-alternating polarity across it.

 Four-Diode Full-Wave Bridge Rectifier
Notice that ac voltage from the bottom terminal of the transformer is applied to the bridge where the cathode of diode 1 and the anode of diode 4 are connected, and from the top terminal of the transformer where the cathode of diode 2 and the anode of diode 3 are connected.
The output for the bridge circuit will have its positive dc voltage terminal at the point where the cathode of diode 3 and diode 4 are connected, and the negative point of the circuit will be where the anode of diode 1 and diode 2 are connected.
The equations for calculating the dc average voltage at the output of the four-diode bridge are similar to the two-diode full-wave bridge except the equations for the four-diode bridge must account for a 0.7 volt drop in each of the two diodes used to rectify the positive and negative half-cycles.

 [No title]
The circuit is known as the bridge rectifier because of the similarity of its configuration to that of the Wheatstone bridge, does not require a center-tapped transformer, a distinct advantage over the full-wave rectifier circuit.
The bridge rectifier circuit operates as follows: During the positive half-cycles of the input voltage, Vs is positive, and thus current is conducted through diode D1, resistor R, and diode D2.
This is somewhat of a disadvantage of the bridge rectifier.

 Rectifier - Wikipedia, the free encyclopedia
When just one diode is used to rectify AC (by blocking the negative or positive portion of the waveform) the difference between the term diode and the term rectifier is merely one of usage, e.g., the term rectifier describes a diode that is being used to convert AC to DC.
However, in a circuit with a non-center tapped transformer, four rectifiers are required instead of the one needed for half-wave rectification.
A full wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output by reversing the negative (or positive) portions of the alternating current waveform.

 Single-Phase Half-Controlled Bridge Rectifier
In a semi-controlled rectifier, control is effected only for positve output voltage, and no control is possible when its output voltage tends to become negative since it is clamped at zero volt.
and the output of the bridge is clamped at zero, assuming that the on-state drops across devices in conduction is zero.
It is also possible to build a semi-controlled full-wave bridge rectifier as shown by the circuit in configuration 2.

 The Synchronous Rotary Mechanical Bridge Rectifier   (Site not responding. Last check: 2007-10-31)
However, modern semiconductor rectifiers are not altogether happy with high levels of rf and have limits to their current capability and peak inverse voltage tolerance.
The stationary electrodes of the bridge can be most clearly seen at the front of the array, where on the left hand side of the motor, two stationary electrodes are commoned at the top and connected to one of the chokes by a downcoming vertical wire.
The action of the bridge should need no further explanation - it's a pretty simple piece of technology, and a semiconductor bridge simply replaces the rotating mechanical switches by solid state ones, so if puzzled you ought to be able to figure it out from there.

It is also useful for translating a DC input of arbitrary polarity into a DC output of known polarity, as is commonly required in electronic telephones or other telephony devices, and has application in protecting against battery reversal in battery-powered circuits.
In a conventional rectifier bridge, the diodes prevent the backflow of current from the power supply input capacitor as the applied voltage drops below the voltage on the capacitor.
By putting the FET bridge circuit in front of the capacitor, a polarized capacitor could be used instead which may be advantageous in terms of size and cost.
