Power supply smoothing is a technique used to reduce fluctuations in electrical voltage, ensuring a steady output. This is important because many electronic devices, such as computers and audio equipment, require stable power to function properly. Smoothing is typically achieved using components like capacitors and inductors that filter out noise and spikes in the voltage.
The process involves charging and discharging these components to maintain a consistent voltage level. When the power supply fluctuates, the capacitors can release stored energy to fill in gaps, while inductors resist sudden changes in current. This results in a cleaner, more reliable power source for sensitive electronics.
