Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFPeak Inverse Voltage(PIV):
The maximum voltage across a reverse bias diode is known as Peak Inverse Voltage.
PIV for different rectifiers is shown below:
- Half Wave rectifier: Vm
- Full Wave centre tap rectifier: 2Vm
- Full Wave Bridge rectifier: Vm
Therefore, the PIV of a conducting and a non-conducting diode in a bridge rectifier is Vm i.e. Peak value of a.c. input.
