Constant DC voltage is required from a variable AC voltage. Which of the following is correct
order of operation?
- A Regulator, filter, rectifien
- B Rectifier, regulator, filter
- C Rectifier, filter, regulator
- D Filter, regulator, rectifien
Answer & Solution
Correct Answer
(C) Rectifier, filter, regulator
Step-by-step Solution
Detailed explanation
In order of obtain a constant dc voltage from a variable acsource following operations should be performed:1. Rectifier: it
converts full ac signal to pulsating dc signal.
2. Filter: The pulsating dc signal is converted to pure dc signal.
3. Regulator: It provides stable dc voltage independent to the load current and ac source voltage variations.
