Question
In the circuit shown, the input is a sinusoidal AC voltage having an RMS value of V . The worst-case peak-inverse voltage seen across any diode is ______ V. (Round off to 2 decimal places.)
Correct answer
389 to 391
Solution
In a bridge rectifier with a capacitor filter, the Peak Inverse Voltage (PIV) across each diode is equal to the peak value of the input AC voltage, .
Given V .
The worst-case (maximum) RMS voltage is V.
The peak voltage is V.
Therefore, the worst-case PIV is V.
Given V .
The worst-case (maximum) RMS voltage is V.
The peak voltage is V.
Therefore, the worst-case PIV is V.
