Flyback converter ripple current

WebApr 15, 2024 · A: A flyback converter is a simple implementation of a switch-mode power supply (SMPS), and it can be designed to deliver a DC output from either an AC or DC input, with outputs both lower and higher than the supply source (buck/boost operation). WebApr 9, 2024 · Both capacitors have ripple because inductor current rises or falls. You have the output ripple figured out, either the inductor current is large enough so current can charge the cap, or the inductor current is low so cap must discharge into the load. Same goes for the input capacitor.
