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 ...
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.
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 new method of circuit protection allows designers greater flexibility and increased reliability while reducing the time to market. The long-accepted assumption that hundreds of amperes and thousands ...
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 ...
GridON has announced a new family of inexpensive fault current limiters with smaller footprint for mid-to-high-voltage applications. GridON’s established technology has been further enhanced to offer ...
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 ...
