Interactive AI-built app teaches switching power supplies from one coil to a 20V-to-5V USB-C design
techartist_ · x · 2026-11-08
A developer shared an interactive learning app, built with AI, that teaches switching power supply design — a topic usually taught as equations.
The core insight: most of what switching supplies do follows from one fact — a coil resists any change in its current. The app builds lesson by lesson from that single fact, from one coil all the way to designing a 20V-to-5V USB-C supply. A good example of first-principles, AI-generated interactive courseware.
