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. In practice, use of the Vienna rectifier is advantageous when space is at a sufficient premium to justify the additional hardware cost. These include: Telecommunications power suppl. OverviewThe Vienna rectifier is a AC rectifier, invented in 1993 by Johann W. Kolar at, a public research university in Vienna, Austria. . The Vienna rectifier provides the following features: • three-level three-switch PWM with controlled output voltage • Three-wire input, no connection to neutral. . The Vienna rectifier is a three-phase three-switch three-level (PWM) rectifier. It can be seen as a three-phase with an integrated .
