Dynamic load fluctuation

In power supply circuits, this refers to the fluctuation in output voltage when the output current is rapidly changed within a specified range (usually within the rated range) while the input voltage and other conditions are at rated levels. It is one of the indicators of the stability of a power supply circuit, and 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.
