Peak inverse voltage of diode used in half-wave rectifier is Vm. Peak Inverse Voltage is the highest voltage that may traverse a reverse bias diode.
The PIV for several rectifiers is displayed below:
- Half Wave rectifier: Vm
- Full Wave centre tap rectifier: 2Vm
- Full Wave Bridge rectifier: Vm

Half Wave Rectifier
One-half of each a.c. input cycle is rectified in a half-wave rectifier. The p-n junction diode has low resistance when it is forward biassed and high resistance when it is reverse biassed. When the input voltage is provided, the diode is forward biassed for one-half of a cycle, and in the other half, it is reverse biassed. The ideal outcome can be attained during alternate half-cycles.
Advantages of Half Wave Rectifier:
- Affordable
- easy connections
- Simple connections make it simple to utilize
- There are fewer components used.
Disadvantages of Half Wave Rectifier:
- Increased ripple production
- There are harmonics created.
- The transformer is not used very often.
- The effectiveness of correction is poor.
As a result, in a bridge rectifier, the PIV of a conducting and a non-conducting diode is V, or the peak value of the a.c. input.
Summary:
Peak inverse voltage of diode used in half-wave rectifier is. (a) 2Vm (b) Vm (c) Vm/2 (d) Vm/3
Half-wave rectifier diode’s peak inverse voltage is Vm.
