which type of transformer is used for high frequency application?

For high-frequency applications, a high-frequency transformer is typically used. These transformers are designed to operate efficiently at elevated frequencies, often exceeding 20 kHz. They utilize materials like ferrite cores to minimize losses and enhance performance. High-frequency transformers are commonly found in applications such as switch-mode power supplies, RF amplifiers, and signal processing circuits, where efficient energy transfer and compact size are crucial.
