## How do you calculate ripple factor?

Ripple factor = **√(Vrms/Vdc)2-1**=√(Vm/2/Vm/Π)2-1 = 1.21. Effieiency = (Vdc/Vrms)2 = (Vm/Π/ Vm/2)2=0.405X100= 40.5%. Graph : Trace the Input and Output waveform of half wave rectifier without and with filter observed in DSO.

## What is ripple attenuation?

the ripple is **a certain amount of amplification or attenuation tolerated in the pass band of the filter**. So it depends if those effects are critical for your application or not. if you are doing a FFT and the amplitude of the spectrum is key, then a low or no ripple low pass filter is required.

## How do you calculate ripple factor from VDC?

**Vdc = Vac RMS x SQRT2/(1+1/2frc)** ac, rectifier, capacitor filter, load resistor. f is ripple frequency after rectifier, c is Farads, r is OHMS.

## How do you calculate the ripple of a buck converter?

**The waveforms of ripple current and voltage are shown below.**

- Δ V C = Δ Q C.
- = Δ I L 8 f s.
- Δ V C = Δ I L 8 C f s.
