Boost Converters and Buck Converters: Power Electronics
Why Electrical Engineering Stack Exchange recommends it
Electronics Stack Exchange users point people to it for an intuitive, visual picture of how inductors, capacitors and diodes behave in buck and boost converters.
Recommended by 2 people across 2 different months, 2019 to 2023.
What it is
An animated explainer from Eugene Khutoryansky's physics channel on how switching power converters work. It walks through buck and boost converter designs, including naive approaches that fail, showing voltage as height and current as arrow size.

Have a look at [this video] for some good insights into how switching converters work. You should find it helps your understanding.

The following video may be extremely helpful to visually explain the dynamics of buck (and boost) converters, going through different basic (and also incorrect) design ideas and their pros and cons. Voltage is shown as distance (height), and the current magniture by arrow size. The role of inductors and capacitors in a network is especially clarified here. [this video]
Cites user221241 · 2019-05 · Electrical Engineering Stack Exchange · on “Why won't a diode allow current when there is a return path”
I am watching this video. [this video] at 1:05 it shows a diode as "blocking" current, even though there seems to be a return path through the diode and back to the battery via the capacitor or light bulb?
