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 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 ...

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 ...

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 ...
