output ripple

Output ripple is a small, periodic variation or fluctuation in the voltage of a power supply's output. When a device converts electrical energy from one form to another, such as in power supplies, it often causes these tiny waves or ripples in the steady voltage signal. Although usually small, excessive ripple can affect sensitive electronic components, leading to instability or noise in the system. Engineers aim to minimize ripple to ensure a stable and clean power output, which helps electronic devices operate reliably and accurately.
