Dynamic load fluctuation

In power supply circuits, when the input voltage and other conditions are at their rated values, and the output current is rapidly changed within a specified range (usually within the rated range), the resulting fluctuation in the output voltage is referred to as dynamic load variation. It is one of the indicators of power supply circuit stability; the smaller the dynamic load variation, the higher the stability against sudden load changes. It is useful for estimating the stability of the output voltage when connecting loads with large fluctuations.
