1. What are 5 parts of a power supply? Input, rectifier, filter, regula-
tor, protection
2. Which two parts of a power supply are op- Regulator and protection
tional?
3. What is the purpose of a power supply? To convert AC power into
smooth DC power
4. What does the input of a power supply do? Step up or down the AC input
voltage
5. What does the rectifier do in a power sup- Changes AC into pulsating
ply? DC
6. What does the filter do in a power supply? Changes pulsating DC into
smooth DC
7. How type of components do filters use? Reactive components
8. What does a regulator do in a power supply? maintains the output voltage
at a constant level despite
changes in load current
9. What does the protection circuit do in power Prevents damage to pow-
supply? er supply if load becomes
faulty, limits or disables out-
put
