How does a simple inductor, capacitor, and switch turn a tiny DC voltage into something dramatically higher? In this video, we go deep into the real physics behind the boost converter—the part most textbooks skip. You’ll see the entire process visualized with intuitive analogies: • how energy builds inside an inductor • how a capacitor steps voltage upward one pulse at a time • why switching at the right moments changes everything • and how engineers use this trick to generate voltages far beyond the input supply Whether you're into electronics, power engineering, or just love understanding the hidden mechanisms behind modern devices, this breakdown will finally make boost converters feel obvious. 🔧 What you’ll learn: – The true role of the inductor in stepping up voltage – Why the diode makes the circuit work – How the switch controls energy flow – The volt-second balance rule (and why it matters) – The classic boost converter equation: Vout = Vin / (1 – D) 📘 Related videos (recommended before watching): • Inductors explained : • Capacitors explained : • RL and RC circuits : • Buck converter : 💡 Working on an educational or engineering project?
