Dynamic load fluctuation

In power circuits and similar systems, this refers to the variation in output voltage when the input voltage is within rated conditions and the output current suddenly changes within a specified range (usually within 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. This is useful for estimating the stability of the output voltage when a load with significant fluctuations is connected.
