Voltage clamping is a technique used to limit the voltage in an electrical circuit to a specific level. This is often achieved using devices like Zener diodes or voltage clamps, which prevent the voltage from exceeding a predetermined threshold. By doing so, voltage clamping protects sensitive components from damage due to voltage spikes or surges. In practical applications, voltage clamping is essential in various electronic devices, including power supplies and microcontrollers. It ensures that the voltage remains within safe limits, enhancing the reliability and longevity of the equipment. This technique is widely used in both consumer electronics and industrial systems.
