In a DC/DC converter, a triangular-wave switching (inductor) current is output. this current charges an output capacitor, and so a triangular-wave voltage, due to the output capacitor ESR (equivalent series resistance) × switching current, appears at the output. The amplitude of this voltage is called the ripple (pulsating) voltage.
