Diodes and Applications - Technical MCQs

Q1:

Which of the following circuits would require the least amount of filtering?

A A half-wave rectifier

B A full-wave rectifier

C A bridge rectifier

D A full-wave rectifier and a bridge rectifier

ANS:D - A full-wave rectifier and a bridge rectifier

The circuit which gives very less ripple with high rectification efficiency is require least filtering. Out of C AND D we will choose C as the best option because in comparison to a center-tapped, bridge is more efficient though it's drop is more across the diodes (4 diodes in bridge).
