# How To Calculate Theoretical Ripple Voltage

Contents

## How do you calculate ripple voltage?

Alternatively, we can derive a simple expression for the ripple voltage. If the ripple is small, we can assume that the current through the load is constant, and from I = C(dV/dt) we have ΔV = (I/C)Δt. Δt is just the period of the ripple, so it equals 1/f, making the expression ΔV = (Iload/fC).

## How do you calculate the ripple voltage of a full wave rectifier?

Ripple voltage of the full wave rectifier is Vr(rms) = (2.4*Idc)/c. = (2.4*40*10^-3)/(75*10^-6). = 1.28v. 2.4*40/75 = 1.28.

## What is theoretical ripple factor?

The ripple factor is defined as. The ratio of the RMS value of an alternating current component in the rectified output to the average value of rectified output. The ripple factor is denoted as γ. It is a dimensionless quantity and always has a value less than unity.

## What is ripple voltage?

Acceptable ripple voltage is about 100mV peak to peak. Majority of good power supplies have ripple and noise figures of better than 10mV rms, while SMPS figures of 50mV or less are possible, however, higher current supplies are likely to have slightly higher values.
