![]() Therefore, if in place of single phase transformer we use three phase transformer the ripple factor can be reduced up to a large extent. Thus, the Smoothing circuit is used, filter works as a smoothing circuit for rectifier system.īut after this smoothing process the rectifier voltage falls to zero at some point. If this pulsating DC voltage is used in several applications it lead to poor performance of the device. These ripples are the AC components in the DC voltage. Thus, in such types of arrangement we need smoothing circuit in order to remove these ripples. While in case of half wave rectifier the value is quite large but in full wave rectifier too the value of rectifier is significantly large. In both the cases the value of ripple factor cannot be neglected. ![]() In case of half wave rectifier the ripple factor is 1.21 and in case of full wave rectifier the ripple factor is 0.482. ![]() The drawback of this arrangement is high ripple factor.
