  • In a full-wave rectifier during a positive half cycle, one diode conducts and gives the output similarly in the negative half cycle another diode conducts and gives the output.
  • In a full-wave rectifier, the current in each diode flows for the half cycle of the input signal.
  • The average current flowing through each diode in a full wave rectifier Half of the average value of the load current
