Abstract: This manuscript centers on the design of a shell-type solid-state transformer with Litz wire winding using convex optimization techniques. The primary goal is to minimize the mass, core, and ...

Unique Technology Eases Transportation Challenges Rincon, GA, January 2012 – Efacec Power Transformers Inc. has successfully shipped the largest shell transformer made in the U.S. in more than 20 ...

Abstract: When a disconnecting switch in a gas insulated switchgear (GIS) operates, a high frequency oscillating surge called very fast transient (VFT) is generated. The VFT may set off overvoltage in ...

The core provides a path for magnetic flux and is typically constructed from high-permeability silicon steel to minimize losses. Laminating the core into thin sheets reduces eddy current loss and ...
