Explanation:
Half wave and full wave rectifiers are used to convert AC voltage to DC voltage. During the process of rectification, a diode is used to allow current flow in only one direction. This results in a DC voltage that is either positive or negative, depending on the type of rectifier used.
Peak Inverse Voltage (PIV) is the maximum voltage that a diode can withstand in the reverse direction. It is important to choose a diode with a PIV rating that is greater than or equal to the maximum reverse voltage that will be applied to it.
For both half wave and full wave rectifiers, the PIV is equal to the maximum voltage of the input signal, since this is the voltage that the diode will experience in the reverse direction.
However, the output voltage of a half wave rectifier is equal to the peak value of the input voltage, while the output voltage of a full wave rectifier is equal to the average value of the input voltage.
Therefore, the PIV of a half wave rectifier is smaller than the input voltage, since the peak voltage is smaller than the maximum voltage. On the other hand, the PIV of a full wave rectifier is greater than the input voltage, since the average voltage is smaller than the peak voltage.
Conclusion:
In summary, the Peak Inverse Voltage of a rectifier depends on the type of rectifier used. For a half wave rectifier, the PIV is smaller than the input voltage, while for a full wave rectifier, the PIV is greater than the input voltage. It is important to choose a diode with a PIV rating that is greater than or equal to the maximum reverse voltage that will be applied to it.
