The Vienna rectifier offers several advantages, including high efficiency due to its ability to reduce conduction losses, which makes it suitable for applications requiring energy savings. It also provides a compact design with fewer components, leading to reduced size and weight. Additionally, the Vienna rectifier can handle a wide input voltage range, making it versatile for various power systems. Its ability to produce low total harmonic distortion (THD) enhances the quality of the output power.

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.

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.

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.
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.
