Question

Is ripple current AC? What is the difference?

Answer 1

Amplitude. Ripple usually refers to DC that has been rectified, as in audio equipment, but not completely filtered, so that small AC component gets through. It is commonly heard as a hum.

I hear of one guy who was so fanatic about getting rid of it he built a power supply on a separate chassis, which he put in the basement. Sounded great.

Answer 2

Alternating current,the waves oscillate in a regular   pattern              and we call it sine wave. It got a correct frequency and wave length. But ripples are irregular.

Answer 3

Ripple usually refers to a small amount of unwanted a.c. superimposed on d.c.

In a power supply, the ripple current is supposed to flow through a smoothing capacitor, which blocks d.c., while the smooth d.c. flows to the output. However, unless the capacitor is infinite (impossible), some of the ripple will flow to the output.

Semiconductor regulators can greatly reduce the effect of ripple.
