Explanation: Filter converts the pulse waveform from the output of the switch into a dc voltage. Since this switching mechanism allows a conversion similar to transformers, the switching regulators is often referred to as a DC transformer. 11. Which of the following is considered to be the most important components of the switching regulator?
A. RC or RLC filter
B. RL or RLC filter
C. ORC or RL filter
D. RC, RLC or RL filter
Answer:A

Which of the following is considered to be the most important components of the switching regulator?
A. RC or RLC filter B. RL or RLC filter C. ORC or RL filter D. RC, RLC or RL filter
Explanation: RL or RLC filter is the most important components of the switching regulator, because there are several areas that are affected by the choke of inductor including energy storage for the regulators output ripple, transient, response etc. 12. Which is the most commonly used low voltage switching regulators?
