Question
In the circuit shown, the input Vi is a sinusoidal AC voltage having an rms value of 230 V ± 20%. The worst case peak-inverse voltage seen across any diode is _______ V. (Round off to 2 decimal places)
Answer :
390.266
The given circuit is a full-wave bridge rectifier.
Given input Vi is a sinusoidal AC voltage having an RMS value of
Vrms = 230 V ± 20%
The worst-case peak-inverse voltage seen across any diode is
Vm = √2 × maximum value of Vrms
Vm = √2 × (230 + 0.2 × 230)
Vm = 390.32 V
