Digital microprocessor-controlled power converter technology, both for DC and AC drives, has
now reached a level of technical sophistication
which (in purely technological terms) enables
almost any drive job to be handled both with DC
and AC drives. Nevertheless, the conventional
DC drive (in both its 1-quadrant and 4-quadrant
variants) will continue to play an important role,
for technical and physical reasons alike, when
dynamic drives with a constant load torque and
stringent requirements for overload withstand
capability throughout a large speed setting range
are involved.
