Capacitor Filter C-Filter
Capacitors serve a critical filtering function in power supplies, because an ideal power supply produces a flat DC waveform rather than the pulsating DC output of a rectifier. Most power supplies therefore utilize a rectifying circuit followed by a filter circuit that includes at least one smoothing capacitor.
Why the Capacitor in Your Power Supply Filter is Too Big
The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used.
