Diodes and Applications - Technical MCQs

Q1:

A filtered full-wave rectifier voltage has a smaller ripple than does a half-wave rectifier voltage for the same load resistance and capacitor values because:

A there is a shorter time between peaks

B there is a longer time between peaks

C the larger the ripple, the better the filtering action

D none of the above

ANS:A - there is a shorter time between peaks

Since FW Rectifiers have output frequency than HW Rectifiers the time between peaks for the FW Rectifiers would be shorter since f=1/T and the time between peaks for the HW Rectifiers would be longer which would explain why HW Rectifiers have more ripple.
