Answer Posted / sunil guru
one method can b used
firstly rectify the AC to DC then with the help of DC
chopper(DC-DC converter)convert 2 required voltage then to
provide that voltage 2 gate of MOSFET OR IGBT(full DC is
given 2 MOSFET ONLY CONTROLLED VOLTAGE IS GIVEN 2 GATE OF
MOSFET OR IGBT) and thus by giving the controlled voltage
to armature speed can be controlled
AND MOST COMMON 3 METHODS R THERE TO CONTROL SPEED OF DC
MOTOR
1.ARMATURE VOLTAGE CONTROL
2.FIELD FLUX CONTROL
3.ARMATURE RESISTANCE CONTROL
