R&D engineers have traditionally found it a challenge to measure dc inrush current and current during dc voltage transients because these measurements require complex setups with multiple pieces of ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

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 ...

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 ...
