AI Customer ServiceThis PLECS demo model shows a Vienna Rectifier with an output voltage of 700 V and an output power of 12.25 kW. The simulation combines the electrical power circuit and the cascaded controls. The Vienna Rectifier is a unidirectional three-phase three-switch three-level PWM AC-DC converter: The controls are modeled with functional subsystem blocks.
The Vienna rectifier power topology is used in high-power, three-phase power factor correction applications such as offboard electric vehicle (EV) chargers and telecom rectifiers. Control design of the rectifier can be complex. This design guide illustrates a method to control the power stage using C2000TM microcontroller (MCU).
The Vienna Rectifier is a pulse-width modulation rectifier, invented in 1993 by Johann W. Kolar at TU Wien, a public research university in Vienna, Austria. The Vienna Rectifier provides the following features: The Vienna Rectifier is a unidirectional three-phase three-switch three-level Pulse-width modulation (PWM) rectifier.
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. Fig. 2: Top and bottom views of an air-cooled 10kW-Vienna Rectifier (400kHz PWM).
Traditionally, hysteresis-based controllers have been used for Vienna rectifiers. Only recently have sine triangle-based PWM been shown to work for Vienna Rectifier control. This control can be quite challenging to design.
