In the circuit shown, the input

{V}_{ {i}}

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.)

Solution:

V_{r m s}=230 ± 20 \%

V_{r m s}=(230+20 \%)

V_{r m s}=230+46=276

PIV for the given circuit is to be

V_{m}=V_{\;\text "rms "\;} × √{2}

=276 × √{2}=390.26 {V}
