Hello,
Why frequency response (for ex: Bode Plot) will be taken for stability analysis for buck converter? We don't use AC in buck converter. But why it needs to be studied for frequencies zero to infinity? One of my friend tested a buck converter by giving a small AC voltage at one of its ports. I didn't get the logic there?
