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.

bridge rectifier is the best rectifier.
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.
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
The population of International Rectifier is 2,009.
International Rectifier was created in 1947.
Efficiency is double in case of full wave rectifier.
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
