Abstract:

The phase-controlled dc drive operation is well established, however, this paper investigates the operation of the separately excited dc machine in each of the four quadrants when fed by the symmetrical multipulse modulated, improved power quality, single-phase, dual buck converter. The armature control of the dc machine with constant load torque is undertaken in both clockwise and anticlockwise directions in the motoring and generating modes. The performance of the drive in each quadrant is compared with that of the conventional phase-controlled one. The simulation results indicate, at the ac interface the harmonic profile of the proposed drive fed by the improved power quality dual converter can be manipulated to enable use of more economical filters compared to those in the phase-controlled one.
