Why the Capacitor in Your Power Supply Filter is Too Big
The general idea of the design is that we want all of the ripple power ([P_{o}cos(2omega t)]) to flow back and forth to the ripple port capacitor. To get this to happen, we need the ripple power equation to match the equation for the power to a capacitor. The equation for the power to a capacitor in a sinusoidal AC circuit is
