INTRODUCTION
Steel rolling mills, paper mills, printing presses and textiles mills employing DC motor Drives
Earlier, dc power was obtained from motor-generator (MG) sets or ac power was converted to dc by means of mercury-arc rectifiers or thyratrons.
The advent of thyristors has changed the art of ac to dc conversion.
Presently, phase controlled ac to dc converters employing thyristors are extensively used for changing constant ac input to controlled dc output voltage.
