Answer Posted / abhimannu nayak
drives are used only for motion control so if you are
talking about ac or dc drives then both are only used for
motor speed control by controlling ac or dc output voltage
DC drives are used for DC motors speed control whereas ac
drives are used for AC motors . Moreover DC drives have
only converter whereas ac drives have both converter and
inverter . in DC drives , thyristors are normally used for
converter whereas in Ac drives , thyristors/IGBT/ IGCT are
used dependong on the applications
DC drives performing the following functions:
1.speed control of DC motors
2.Breaking by applying resistance at rotor.
3.uses converter and chopper.
AC drives performing the following functions:
1.speed control of AC motors
2.Breaking/accelerating by changing the frequency of the
supply.
3.uses converter and inverter
