1. Explain how the dc voltage of a
full-wave rectifier is improved when a capacitor filter is used. Draw waveforms
of the load voltage and the diode current.
2. Derive expressions of the
percentage regulation for a half-wave, full-wave and a bridge rectifier circuit
each employing the same capacitor and the same load resistance.
3. What is a voltage multiplier?
Draw the circuit diagram of a half-wave voltage doubler and explain its
operation. What is the advantage of the circuit?
