Transformer Cores
Some transformers feature ferrite cores, which act as a means to transfer magnetic flux within the transformer. While less common than laminated iron cores, ferrite cores allow for superior performance.
How transformer ferrite cores work
These devices are commonly parts of switched-mode power supplies. The ferrite in the core is in powdered form, which allows the transform...
