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 ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

Many applications today, including industrial machinery, power tools and other high current equipment, use limiting inrush current as a major design consideration to combat the problematic effects of ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...

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 ...

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 ...
