Why the Capacitor in Your Power Supply Filter is Too Big
January 21, 2016 by David Williams. 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. All AC-DC converters, whether they are linear supplies ...
