Half-wave Rectifier

For the half-wave rectified signal:

Vdc = 0.318 Vm

If the effect of VT is also

considered, the output of the

system will as below

Vdc = 0.318 (Vm- VT)

Effect of VT on half-wave rectified signal

PIV rating of Half-wave Rectifiers

PIV rating is very important consideration for rectifier circuits

For the half-wave rectifier must be equal or must not exceed the peak value of the applied voltage

· PIV ≥ Vm

This is the voltage rating that must not be exceeded in the reverse bias region

When vin is negative.

• The total effect of diode on the output signal is given in below

Average voltage VAV

• The average d.c. value of this half-wave-rectified sine wave is
