The diode bridge is a simple circuit used to convert alternating current (AC) into direct current (DC). In this guide, you’ll learn how it works, what it’s used for, and how you can build your own.

Even though you may not notice it, the diode bridge is everywhere. When you charge your phone or laptop, or you turn on the TV, you directly engage the diode bridge. How? All these devices rely on a diode bridge to transform the AC voltage from your wall outlet into a DC voltage that your device can use.
