Power Supply and Voltage Regulator

What are the components of a power supply?

• Filters, rectifiers, and voltage regulator

• Transformers and capacitors

• Diodes and resistors

• Inductors and switches

What is the function of a transformer?

• To step down or up the AC voltage

• To convert AC to DC

• To filter the output voltage

• To regulate the voltage

What does a rectifier do?

• Converts AC to pulsating DC

• Filters the output voltage

• Regulates the voltage

• Steps down the voltage

What is the purpose of a capacitor filter?

• To smooth out the output voltage

• To increase the voltage

• To decrease the current

• To convert AC to DC

What is the primary function of a voltage regulator?

• To maintain a constant output voltage

• To convert AC to DC

• To filter the output voltage

• To step down the voltage

What happens to the output voltage when the load changes?

• It remains stable due to load regulation

• It increases significantly

• It decreases to zero

• It fluctuates wildly

What is the role of a diode in a power supply?

• To allow current to flow in one direction

• To store electrical energy

• To convert DC to AC

• To step up the voltage

How does a switching regulator differ from a linear regulator?

• It provides a constant output voltage

• It is simpler in design

• It is more efficient and can handle higher power

• It only works with AC input

What is the function of an inductor in a power supply circuit?

• To filter high-frequency noise

• To regulate the output voltage

• To convert AC to DC

• To store energy in a magnetic field

What is the main role of a voltage regulator?

• Increase the input voltage

• Convert DC to AC

• Maintain a constant output voltage

• Remove all ripple
