What does the term 'hunting' refer to in the context of regulatory devices?

The term 'hunting' in the context of regulatory devices refers to oscillation in voltage levels. This phenomenon typically occurs when there is a feedback loop that causes a device, such as a voltage regulator, to overcorrect for changes in voltage. As the regulator attempts to maintain a stable output, it may oscillate around the desired set point, leading to fluctuations in voltage levels. This can create instability in the power supply and adversely affect sensitive electronic equipment. Understanding this term is crucial for those working with electrical systems, as it emphasizes the need for proper design and tuning of regulatory devices to prevent undesirable fluctuations in power delivery.
