Dynamic load fluctuation

In power circuits and similar systems, this refers to the variation in output voltage when the input voltage and other parameters are within rated conditions and the output current changes rapidly within a specified range (usually within the rated range). It is one of the indicators of the stability of a power circuit, and the smaller the dynamic load fluctuation, the higher the stability against sudden load changes. It is useful for estimating the stability of the output voltage when a load with large fluctuations is connected.
