WebSo as duty cycle is more the average DC voltage supplied to motor is more and so speed of motor is increased. So as duty cycle is varied by varying on and off time of chopper, the speed of motor can be varied. The given circuit demonstrates one of such chopper circuit using Zero Cross Detector (ZCD), timer IC NE555 and darlington amplifier ... WebAug 26, 2015 · Choppers convert fixed dc voltage into variable dc voltage. Duty cycle is defined as the ratio of ON time to the total time period. The total time period of one cycle …
