As we have seen, ripple, a small but regular variation in the dc output voltage and current of a charger, is an unavoidable consequence of converting ac power to dc power. Large amounts of ripple can affect battery life and pose a risk of equipment damage. Reducing the magnitude of ripple voltage and/or current is the job of a dc filter.

Input filter caps need to be able to supply a quick burst of energy and to suppress noise generated in the switch circuit. Important considerations for the input filter cap are ESR, ESL, and ripple current. High CV density is preferred in the input filter caps to reduce board space, although it is more critical for the output filter caps.
