using vienna rectifier
We can use it as a rectifier and switch
Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
bridge rectifier is the best rectifier.
using vienna rectifier
The Vienna Rectifier is a unidirectional three-phase AC/DC converter of boost-type with sinusoidal input currents and controlled output voltage. It only employs three power switches which makes the Vienna Rectifier immune against short-circuit of the DC-link, cost-effective and reduces the blocking voltage of all its semiconductors by a factor two. It was invented by Prof. Kolar, ETH Zurich. Find more information on www.ipes.ethz.ch.

Small size Low cost Low weight Easy Repalcement
A bridge rectifier will rectify both halves of a sine wave and give "continuous output" through 360 degrees of the input. Oh, and you don't need a center-tapped transformer to use it.
bridge rectifier is the best rectifier.
you only use half the number of windings in the bridge comparing it to the center tapped , and in the bridge rectifier the peak inverse voltage that a diode must be able to sustain without break down is half of that in the center tapped PIV per diode: center tapped: 2Vm : bridge : 1Vm
Working the rectifier
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.
