2. Rectifiers and Filters

Try these first

1. 1.

   What is the main function of a rectifier?

   Hint

   Think about the types of currents.

2. 2.

   Which type of rectifier only uses one half of the AC cycle?

   Hint

   Recall the word 'half'.

3. 3.

   What type of output does a half-wave rectifier produce?

   • Pulsating DC
   • Steady DC
   • AC

   Hint

   Focus on what part of the wave it uses.

4. 4.

   True or False: A full-wave rectifier requires a center-tap transformer.

   • True
   • False

   Hint

   Think about alternative configurations.

5. 5.

   Design a power supply circuit that incorporates both a half-wave and full-wave rectifier. Explain the design process and the reasoning behind your chosen components.

   Hint

   Consider real-life applications and requirements regarding load current.

6. 6.

   Given a full-wave rectifier setup, simulate the circuit on software and measure the output ripple. Discuss potential ways to minimize ripple further.

   Hint

   Experiment with different values of capacitance in simulations to see real-time effects.
