Offline power supplies that drive loads of 200W and more require inrush-current limiters. Unrestricted inrush currents can reach hundreds of amperes, which may damage the line rectifier, open the fuse ...

A transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open ...

In the development of different technologies, many engineers encounter and have to deal with inrush currents to their devices. The reality of inrush current and the meaning of an I2t measurement will ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

This article addresses a characteristic found in many battery-powered products. When power to a circuit is first applied, high peak currents are encountered during the time taken to establish stable ...
