Fig. 2: Top and bottom views of an air-cooled 10kW-Vienna Rectifier (400kHz PWM). The Vienna Rectifier is useful wherever six-switch converters are used for achieving sinusoidal mains current and controlled output voltage, when no energy feedback from the load into the mains is available.

Wilhelm Bauer, Vienna (active 1884) President of Vienna Clockmakers Society 1881, and active Clockmaker until late 1920s. Produced Post Office/Official Government Vienna Regulators. Some clocks signed "Kreutz & Bauer in Wein". Gebr. Resch, Ebensee, Austria. Used trademark "REMEMBER". Factory began 1862 in Vienna, moved to Ebensee 1871.
A rectifier used in high-voltage direct current (HVDC) power transmission systems and industrial processing between about 1909 to 1975 is a mercury-arc rectifier or mercury-arc valve. The device is enclosed in a bulbous glass vessel or large metal tub.
Johann Sahulka (born 25 February 1857, Deutsch-Wagram - 8 October 1927, Vienna) was an Austrian scientist and professor of electrical engineering at Vienna University of Technology. He discovered that mercury arcs act as a rectifier. [1]
For a three-phase SMPS, the Vienna rectifier configuration may be used to substantially improve the power factor. SMPSs with passive PFC can achieve power factor of about 0.7–0.75, SMPSs with active PFC, up to 0.99 power factor, while a SMPS without any power factor correction have a power factor of only about 0.55–0.65.

A rectiformer is a rectifier and transformer designed and built as a single entity for converting alternating current into direct current. It is piece of power systems equipment rather than an electronics component. Rectiformers are used for supplying power to different field of ESP (electrostatic precipitator).
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
