Modern transformers are designed with high-permeability core material to lower losses and noise levels. During energization, the transformer enters the ultrasaturation region and loses properties such ...

Air-core planar transformers are attractive alternatives to ferrite-core transformers for high-frequency power converters, such as LLC resonant converters. Although many design methods have been ...

The ferrite cores handle more power, work even when hot, and come in many shapes for use in energy, transport, and medical devices.
