EE EFD Series High Frequency Transformers
A transformer is an electrical device that transfers energy between two or more circuits by electromagnetic induction. A changing current in the primary winding of a transformer creates a changing magnetic flux in the core and a changing magnetic field on the secondary winding. The changing magnetic field in the secondary winding induces a changing electromotive force (emf) or voltage in the secondary winding. Most of today’s electronic devices rely on high-frequency transformers, such as those used in telecommunications, switching power supplies, and AC-DC and DC-DC converters. Therefore, the quality and design of high-frequency transformers are crucial to prevent failure and damage. Feel free to contact us for any application needs.
