Hello friends, I hope you all are doing great. Today, I am going to share the new Inductor Library for Proteus . An inductor is the quiet partner of every power supply: in a phone charger, a laptop adapter, an LED driver or the little boost module that makes 12 V from a USB port, an inductor stores energy in a magnetic field a few thousand times a second and hands it on. On a schematic it is just a coil with a value. In real life it has two current limits, a resistance that turns current into heat, and a core that can fill up. Choosing the wrong one is one of the most common reasons a converter runs hot or fails.
