Match each rectifier topology with its peak inverse voltage.

List I

A. Half-wave

B. Centre-tapped full-wave

C. Bridge

List II

P. The input peak

Q. Twice the half-winding peak

R. The secondary peak

Select the correct match.

  • A.A-P, B-Q, C-R
  • B.A-Q, B-P, C-R
  • C.A-R, B-Q, C-P
  • D.A-P, B-R, C-Q

Answer: A

The correct pairing is A-P, B-Q, C-R, and the centre-tapped case is the one that catches people out because its idle diode sees both half-windings at once. The bridge and the half-wave circuit both need only the single peak. Working out what the non-conducting device stands off, rather than what the conducting one carries, is the habit these ratings reward.
