Ripple current in capacitors.
2) Ripple current is the current flowing into and out of the capacitor. It can be from the charging pulses coming from the rectifier or it could be the current demand pulses from the output stage. As the current flows in and out it passes through the ESR and causes heating. Basically the lower the ESR the higher the ripple rating.
