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 ...

What is a pre-charge circuit and what role does it play? The fundamental elements of a pre-charge circuit. Some basic best practices and where to find more information. A common challenge in systems ...

The methods of protecting electronics from circuitry failures and managing inrush current at power on has evolved significantly from a simple fuse and maybe a P-channel FET to much more sophisticated ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

A simple approach based on original research attacks inrush currents at the source - the power transformer. The use of special core materials and transformer design/construction techniques overcomes ...
