Question
Download Solution PDFA diode rectifier circuit has an AC input voltage of 230 Vrms and a load resistance of 1 kΩ. If the diode is ideal and the circuit is a half-wave rectifier, what is the Peak Inverse Voltage (PIV) across the diode?
Answer (Detailed Solution Below)
Detailed Solution

The maximum value of the reverse voltage that a PN junction or diode can withstand without damaging itself is known as its Peak Inverse Voltage.

Calculation
Given, Vrms = 230V
The PIV across the diode is given by:
\(V_{PIV}=\sqrt{2}\times V_{rms}\)
\(V_{PIV}=\sqrt{2}\times 230\)
VPIV = 325 V
