Federal agency computers once required rooms full of equipment, but today, much of that computing power has moved to desktops, laptops and even smaller devices. Smartphones and tablets now have as ...

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

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 ...

With phones charging, gaming consoles starting up, and laptops buzzing as you work, the two standard outlets near your desk or bedside table can get overloaded rather quickly. To avoid blowing a fuse ...

Case study examines a common PV inverter failure that can drive uncommon issues in the field — namely, damage to the AC protection equipment from DC fault currents for short periods during transformer ...
