Consider a capacitor filtered full wave bridge rectifier circuit. The ac input to the
transformer is 230 V rms at 50 Hz. Given that the maximum reverse voltage across a
non-conducting diode is -19.3 V, and the peak to peak ripple voltage (Vr(p-p)) is 10% of the
peak output voltage (V(op)) across the filter capacitor, and the load across the filter
capacitor is 1000, assume constant drop diode model and determine the following:
i) Percentage ripple factor (r %).
ii)Magnitude and voltage rating of the filter capacitor
iii)Diode PIV and the transformer turns ratio.
