Tackling Voltage Peaks > 자유게시판

Managing temporary and elevated energy surges with circuit components is a crucial aspect of circuit design, particularly when dealing with energy-efficient devices. Inrush current refers to sudden surge in voltage that is present when a device is initially powered the device or when a storage element is charged starts charging up.

The high peak current may result in voltage drops to electronic components, overheating of circuit parts, and damage to the power. To address inrush current with components, designers employ various approaches that can be broadly categorized into two main categories: reactive and active solutions.

Passive approaches focus on using electronic components to limit or inrush current. One approach is the use of inrush current limiting (ICL) resistors, which are a small loss in voltage, thereby the peak current. However, ICL devices are more commonly used in scenarios that require a significant reduction in inrush energy surges is not required.

A more efficient way to handle the use of temperature-dependent devices exhibit a high resistance at low low resistance at high temperature readings, and a low resistance at. When a device is turned on for the first time, the high peak current leads to the increase of resistance, reducing the impact of current. Once the device has started normally, the thermistor cools down, and its resistance.
