Precise automatic core loss measurement in higher frequency

Soft magnetic components made of ferrite play an important role in electric components as they are used in a broad range of applications from low-frequency applications such as yokes for micromotors, to high-frequency applications such as flyback transformers, deflecting yokes, high-frequency transformers and magnetic heads. In actual operation, these magnetic components display characteristics different from DC magnetic characteristics or characteristics measured with an LCR meter.
