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

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.
