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?
A. Powdered Permalloy toroids
B. Fermite EI, U and toroid cores
C. Silicon steel EI butt stacks
D. None of the mentioned
