What is a three-phase AC/DC Vienna converter?

A three-phase AC/DC VIENNA converter has been designed to behave as a LFR for PFC because of the action of an appropriate sliding-mode control loop in each phase. The VIENNA rectifier supplies a DC regulated bus in a micro-grid architecture that employs two AC sources, that is, the grid and a small power wind generator.

Are Vienna Rectifier topologies useful for electric vehicle charging systems?

The paper primarily concentrates on various Vienna rectifier topologies. The technology, characteristics, benefits, and operational aspects of Vienna rectifier topologies are vital to improving the performance, efficiency, and grid integration of electric vehicle charging systems.

Can a Vienna Rectifier be used in EV charging stations?

Few studies have examined and quantified the efficiency and losses associated with a particular topology, and none have assessed Vienna rectifier topologies that are substitutes [, , ]. Because it is efficient, small supports regenerative braking, and works with the grid, the Vienna rectifier could be used in EV charging stations.
