A current-limiting circuit is often needed to protect the most expensive parts of the circuit from transients such as current spikes, which occur when a power supply is driving a large capacitive load ...

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 ...

I use an old ATX PSU as a bench supply for my projects and needed a simple & cheap adjustable current limiting circuit. I use an old ATX PSU as a bench supply for my projects and needed a simple & ...

Fault protection is a critical function of all power supply controllers. Nearly all applications require some kind of over-load protection. For peak current-mode controllers this is easily ...

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 ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...
