The internal switch in the rectifier topologies is exclusively activated during the charging of the upper capacitor. 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.
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.
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.
Linking the central junction of the converter to the midpoint of the DC capacitor causes it to use two loads and renders it useless. This is the most significant problem of the converter. Due to its reduced magnetic space and consistent DC voltage, the Vienna three-level rectifier input stage is ideal.
