Ripple factor of half wave rectifier is _________(a) 1.414(b) 1.21(c) 1.3(d) 0.48This question was addressed to me during an interview.Enquiry is from Halfwave Rectifier in chapter Diode Circuit of Analog Circuits

Answer»

Correct choice is (b) 1.21

The explanation: RIPPLE factor of a rectifier is the measure of the EFFECTIVENESS of a power supply filter

in reducing the ripple voltage. It is calculated by taking ratio of RMS AC COMPONENT of output voltage to DC component of output voltage.

r = √Irms^2 – IDC^2/IDC

For a half wave rectifier, it is 1.21.
