Answer / tarequl islam mukul

It can set a trigger voltage,then the output current and voltage varies and the desired dc current can be achieved for motor.

Answer / gagan gumar gupta

we can easyly change firing angle of thyristor from 0-180
it is also economical.its speed control is so fast than any
other thing.

Answer / rehan

the main advantage is that ........ we can switch on and
off the device nd vary the waveform in accordace 2 the
firing angle with the same ckt
