Ripple is the AC component that rides on the DC output of a Rectifier. Most DC power supplies (rectifiers) used in the metal finishing industry are AC to DC converters.

At 24V out, you have about 10V of headroom for the regulator; so you could have several volts of ripple and it won't appear in the output. Assuming a reasonably sized filter cap. An active filter for DC-DC converter ripple cancellation is described and demonstrated. The feed-forward technique used applies to any converter with an output filter inductor. The technique is inherently stable, performs in both continuous and discontinuous conduction modes, and applies to both square-wave and resonant
