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 ...

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 ...

A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that can ...

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 ...

Analysis of the number 2 choice among top Ideas for Design in Electronic Design's 2010 "Best Of" issue deals with protecting open-collector drivers against shorts to the positive rail. The automobile ...

AMES, Iowa - John R. Clem, a physicist at the U.S. Department of Energy's Ames Laboratory, has developed a theory that will help build future superconducting alternating-current fault-current limiters ...

Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

The purpose of this project was to conduct R&D on specified components and provide technical design support to a SuperPower team developing a high temperature superconducting Fault Current Limiter ...

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 ...
