Fullwave rectifier using PN junctionsΒΆ

Objective

Make a full wave rectifier, using two diodes. Two AC waveforms, differing by 180 degree in phase as required. WG and WG bar provide the same.

Procedure

  • Make connections
  • Enable A1, A2 and A3
  • Set WG to 200Hz and adjust timebase to view 4 to 5 cycles

Discussion

Adding capacitors to reduce the ripple is left as an exercise to the user. This experiment is only to demonstrate the working of a full wave rectifier, it cannot provide more than few milli amperes of current.

Why full-wave rectifier is superior to half-wave rectifier ?
