Concept:

  • From the figure, it can be seen that two cycles of output occur for each input cycle of the input voltage.
  • This is because the full-wave rectifier has inverted the negative half cycle of the input voltage.
  • As a result, the output of a full-wave rectifier has a frequency double the input AC frequency.
