Question

Define i) Ripple factor ii) % Regulation

Answer 1

Ripple:-

The output of a rectifier is consists of a dc component and an ac component. This ac component is undesirable and cause for the pulsations in the rectifier output.

So the ac component present in the pulsating output i.e. in the rectifier output is known as Ripple.

Ripple Factor:-

The ratio of r.m.s. value of a.c. component to the d.c. component in the rectifier output is known as ripple factor i.e.

Ripple factor = r.m.s. value of a.c component / value of d.c. component=Iac/IdcRipple:-
