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 ...

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 ...

The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.

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 ...

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 ...

For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the ...

One of the major challenges facing the electric industry is how to manage network fault levels, the magnitude of the electrical current that flows into a fault or short circuit. These current levels ...

On April 14, in Jinchang city, Gansu province, as soon as the command was given, an artificially simulated single-phase instantaneous grounding short-circuit arc was instantly triggered at the ...
