Abstract :
The author proposes a new and simple topology for three-phase buck-mode PFC-rectifier which obtains a very high input-power-factor, high-quality input-line-currents and a regulated output-voltage in buck-mode-range. The proposed rectifier, obtained by modifying a conventional simple topology for three-phase boost-mode PFC, employs new principal of current-synthesis and a simple and unique modulation-technique to improve the input-characteristics. In this paper, the proposed topology, principal of the current-synthesis and the modulation-technique are introduced. Then, experimental results obtained a 2 kW prototype-converter are shown to confirm the validity of the theory
