Experimental study on magnetizing and loss characteristics of electrical strip for different frequencies

This paper mainly aims at studying on the magnetic measurements of electrical strip for different frequencies. The loss coefficient curve and BH curve for different high frequencies can be sketched through the measurement of the transformer using a digital memory oscilloscope. The power of transformer is supplied by an inverter through LC filter and voltage regulator. The cores of experimental transformers are made by the being tested strip with three different rolling directions: paralleling, vertical and mixed to the rolling direction respectively. The influences of different rolling direction for the magnetizing and loss characteristics were investigated. The loss coefficients of mixed rolling direction for different frequencies were measured. The experiment results were analyzed according to two different types of iron loss calculation model, which were the traditional model and the separation model of iron loss contributions.
