Vienna EK three-phase inverter

Vienna EK three-phase inverter

The Vienna rectifier is a unidirectional three-phase three-switch three-level pulse-width modulation (PWM) rectifier. It can be seen as a three-phase diode bridge with an integrated boost converter. OverviewThe Vienna rectifier is a AC rectifier, invented in 1993 by Johann W. Kolar at . 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 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, us. . Figure 3 shows the system behaviour, calculated using the power-electronics circuit simulator. Between the output voltage midpoint (0) and the mains midpoint (M) the common mode voltage u0M appears, a. [PDF Version]

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 suppli.
