Ripple is the AC component that rides on the DC output of rectifier.
Most DC power supplies (rectifiers) used in the metal finishing industry are AC to DC converters. After the AC is converted to DC, there is always an amount of AC that is not converted, and is passed to the output of the rectifier.
Some DC power applications do not react favorably to high amounts of ripple. The amount of ripple that could be present on the output of rectifier will vary depending on the type of rectifier circuit, and what level of output you are operating at (rectifiers that have variable outputs).
