Abstract: VIENNA rectifier is a three-phase three-level boost converter used for active power factor correction (APFC) applications. It utilises an AC switching element in combination with diodes and capacitor to realise it. Three variants of this converter can be arrived at depending on how the AC switching element is realised. This results in variation in efficiency and rating of the components used for a specified power, input voltage, and switching frequency. In this paper all the three variants are simulated, compared, and benchmarked for a 10 kW converter operating on a line voltage of 400 V AC. Design calculations for all the three topologies are provided. Current and voltage rating of various components are calculated. Power dissipated by each and every component is calculated and efficiency between the topologies is compared at switching frequency (f_S) of 50 kHz. The efficiency at different switching frequencies for each topology is calculated and plotted.

Keywords: active PFC; power factor correction; APFC; front end converters; three level converters; VIENNA rectifier topologies; simulation; current rating; voltage rating; switching frequencies.
