Why the Capacitor in Your Power Supply Filter is Too Big

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.
