Novel current injection technique in controlled rectifier

open access: closedThe Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
This paper describes a technique to achieve low harmonic and unity power factor for a three-phase controlled rectifier. The proposed controlled rectifier consists of a thyristor bridge, three bidirectional switches, and a current shaping network. The bidirectional switch is switched at double the line frequency.
