How Does an Inductor Remove Ripple? – The Hidden Art of Smoothing Current

When we talk about computer components, visible parts like CPUs and GPUs often take the spotlight. But behind the scenes, there are essential parts that shape and stabilize the flow of electricity. One such component is the inductor . Often found in VRMs (Voltage Regulator Modules) and power supplies, inductors play a crucial role in removing ripple and delivering stable power. In this article, we’ll explore how inductors eliminate ripple, from the core principle to their practical operation.     1. What is an Inductor? An inductor is a passive electrical component made by winding wire into a coil. When current flows through it, it generates a magnetic field. This magnetic field resists changes in current, which makes inductors excellent at smoothing sudden fluctuations . In simple terms, inductors act as shock absorbers for current , allowing steady current to pass while resisting rapid spikes or dips. 2. What is Ripple? Ripple refers to high-f...
