A carefully considered power inductor is often a key design element to achieve a small, efficient, and cost-effective converter. For many inductor applications, powder cores are clearly superior compared
with alternative core materials, such as ferrites or steel laminations. The designer has many choices in powder core materials and shapes, each offering trade-offs among loss perfo... Read more...

Flyback converters are based on the storage of energy in an inductor during the “on” charging time period t_on, and discharge of this energy to the load during the “off” time period, t_off . For flyback transformers, Magnetics offers distributed air gap powder cores and gapped ferrites.

Powder cores are made of tiny insulated particles,... Read more...
