Custom-designed AC film capacitor
AKMJ-S series
In the output filter of a DC power supply, the job of the capacitor is to maintain a constant DC value by removing as much power ripple as possible. All AC-DC converters, whether they are linear supplies or have some kind of switching element to them, require a mechanism to take the varying power on the AC side and produce a constant power on the DC side.
Generally, a large filter capacitor is used to absorb and store energy when the AC power is higher than what is needed by the DC load, and to supply energy to the load when the AC power is lower than what is needed.
