Pulsating direct current

A pulsating direct current is a direct current (dc) that changes in value at regular or irregular intervals.

A pulsating direct current may change in value, i.e., be always present but at different levels, or it may be a current that is interrupted completely at regular or irregular intervals, but when present, is always in the same direction.

Pulsating currents are commonly created by using diode rectifiers.
