Q.3: A bridge-rectifier circuit with a filter capacitor has RL = 100 ohms. The secondary transformer delivers a sinusoid of 15 V(rms) and has a frequency of 60 Hz. The diodes have VDO = 0.7 V each. Figure 3 (a) What will be the value of the filter capacitor C so that the ripple voltage is limited to below 500 mV peak-to-peak? (b) What is the DC voltage at the output of the system? (c) What is the conduction angle for each diode in the system? Explain with appropriate sketches.
