Abstract: A measurement apparatus includes an Epstein frame, an alternating power supply, a power analyzer, and an oscilloscope. Electromagnetic coupling modeling on an Epstein frame is performed based on a vector model of a magnetic circuit, where an iron core of the Epstein frame is formed by laminating a silicon steel sheet to be measured, and an excitation coil and a detection coil with the same turns number are wound around the iron core. The measurement process is to first obtain a reference B-H curve that only considers a nonlinear reluctance of the iron core, and then to derive a B-H curve considering an eddy current effect in a magnetic field at any frequency from the reference B-H curve. The method, applicable to a measurement for B-H curves at middle and high frequencies, may obtain much higher accuracy.
