Initial weight estimation based on the initial sketch and the design mission profile is conducted. The estimated weight and other design parameters are used to define the ... Read More

Influence of Air Gap Length and Cross-Section on Magnetic Circuit Parameters new

A. Polit[1], R. Jez[1]
[1]ABB Corporate Research Center, Krakow, Poland

The air gap is one of the most crucial part of magnetic circuits, especially in high-power inductors. It significantly modifies the parameters of magnetic devices by increasing the saturation current, linearizing B-H curve of magnetic circuit and causing a decreasing in the inductance. ... Read More
