Beefy 12V supply
4 parts
The half-wave rectifier scaled up to actually power something: a 470 µF reservoir behind the diode and a 220 Ω load pulling real current. One diode tops the cap up once per cycle, so the load drains it for the whole rest of the period — which is exactly where ripple comes from.
