Understanding current ripple factor

Ripple current is a periodic non-sinusoidal waveform derived from an AC power source characterized by high amplitude narrow bandwidth pulses. The pulses coincide with peak or near peak amplitude of an accompanying sinusoidal voltage waveform.
Ripple current results in increased dissipation in parasitic resistive portions of circuits. The dissipation is proportional to the current squared times resistance. The RMS value of ripple current can be many times the RMS of the load current.
