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 ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

A solar day lamp is a simple, inexpensive device for bringing “daylight” to dark interior spaces whenever the sun is shining. This article provides complete instructions for designing lamps using both ...

Vishay Intertechnology, Inc. (NYSE: VSH) announced that its Vishay Ametherm SL2220007 bigAMP inrush current limiting negative ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

Fault current limiters (FCLs) serve as essential protective devices within modern power systems, mitigating the potentially damaging effects of fault currents. By dynamically increasing their ...

Nexans, a worldwide leading expert in the cable industry, has successfully commissioned the world’s first resistive superconducting fault current limiter (SFCL) based on second-generation ...

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel. Per 2014 NEC Article 100, short ...
