From traditional fuses to eFuses, understanding the advantages, limitations, and use cases of each technology helps engineers ...

Portable electronic systems require external supply from a wall adapter (AC/DC subsystem) to charge the internal battery. Now, battery packs are based on Lithium technology, which decreases the total ...

Many types of surge protective devices (SPDs) and technologies are available on the market. To get the most effective protection at the best value, you need to make a selection based on the most ...

Lighter, smaller consumer devices, such as laptops, cell phones, and iPods, use ASICs with geometries as small as 90 nm. At those geometries, even small levels of ESD (electrostatic-discharge)-induced ...

An ideal protection device must limit the energy going to the load being defended, to a sufficient minimum level, such that the load is not damaged. The protection device must survive this energy ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...
