3-Phase Power Factor Correction, Using Vienna Rectifier Approach and Modular Construction for Improved Overall Performance, Efficiency and Reliability
1.0 Abstract:
While applications for 1-Phase PFC are now familiar and prevalent, the same is not the
case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains
should be candidates of 3-Phase power factor correction, because several advantages
ensue, both to the user of the equipment and to the utility. The Vienna Rectifier approach
to achieve 3-Phase ....etc

Abstract
An active current injection network for a three-phaserectifier is proposed. The proposed circuit uses three bidirectionalswitches operating at low frequency and a half-bridge inverteroperating at high frequency. It also uses an inductor in orderto make the current modulation. Because only 3.7% of the totalpower delivered to the load is processed by the injection network,the proposed converter offers high efficiency, and not only a highpower factor is obtained but also the total harmonic distortion isreduced. Operation, analysi ....etc
