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 ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Ordinary power supply design includes current limiting as a protection feature. In product design, this is usually sufficient in that the engineer decides the loads on the supply by design. However, ...
