The Vienna rectifier maintains an efficiency of 98 %. The overall compactness of the construction is due to its huge power density. Because of this benefit, the charging system based on the Vienna rectifier can be utilized with off-board chargers as well as on-board chargers.
Compared to the circuit with more switches, the one with fewer switches enhances the power factor on the supply side by reducing THD in the line current. Split capacitors on the output side minimize voltage stress on power semiconductor switches in this converter. The Vienna rectifier has three voltages: +V dc /2, 0, and –V dc /2.
Fast charging, grid stability, energy economy, and the smooth integration of electric vehicles into the electrical grid are all made possible by Vienna rectifiers. When used in battery energy storage systems (BESS) for electric vehicle charging infrastructure, Vienna rectifiers allow for effective discharge and charging of the batteries.
The Vienna rectifier has three voltages: +V dc /2, 0, and –V dc /2. Preventing sudden fluctuations in voltage on the output side and reducing voltage stress on the switches are the two main functions of the capacitors located on the output side. Therefore, the converter's price can be lowered.
The efficiency numbers for the Vienna rectifier topology-4 are calculated at a frequency of 50 kHz. are shown in Fig. 15. At voltages higher than 420 V, the Vienna rectifier's efficiency increases. This happens for a variety of input voltages. For topology 4, the efficiency value increases to 98.85 %.
Because of this benefit, the charging system based on the Vienna rectifier can be utilized with off-board chargers as well as on-board chargers. The Vienna rectifier is normally found in power supplies, motor drives, and other similar applications that require careful rectification of three-phase AC to DC.
