The power factor and harmonic components of the utility input line current can be improved by shifting the input voltages" in the Delta/Star connected AC/DC converter as well as in the auto transformer phase-shifted AC/DC convert.

The output voltage of the-pulse AC/DC converter can be controlled by using the thyristors instead of diodes. 

n the Delta/Star AC/DC converter with inductive load. A balanced current can be obtained when the thyristors are triggered with any firing angles.
