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 ...

A. An overcurrent device (typically a fast-acting fuse) that reduces the fault current to a magnitude substantially less than that obtainable in the same circuit if the current-limiting device wasn’t ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...

Most readers are probably familiar with two-terminal current-limiting circuits, which have been around for many years. The circuit is very effective for applications where load current is relatively ...

A previous Idea for Design described a technique for protecting the “pass” transistor in a current-limiting circuit against excessive power dissipation (see “Fault-Protected Current Limiter Keeps Its ...

Siemens develops superconducting fault current limiters for limiting short-circuit currents in the grid. Superconductors show zero resistance below the critical temperature and below the critical ...

Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...
