Abstract In order to meet the requirements of low loss and low noise of intermediate frequency transformer for electric locomotive, the magnetic properties of amorphous alloy of core material for middle frequency transformer are studied in this paper. By simulating the actual working status of middle frequency transformer, the loss properties for the amorphous alloy under non-sinusoidal excitation were measured, and then the traditional Steinmetz loss calculation formula was improved. At the same time, considering the generalization of loss calculation formula under different frequencies, the coefficients of the loss formula were adjusted as variable coefficients. In order to study the vibration and noise of medium and high frequency transformers, the magnetostrictive properties of the amorphous alloy core material were tested and analyzed by a laser tester, and the estimated model of magnetostrictive properties of the core material was established. The effectiveness of the proposed model was verified, which can provide a theoretical basis for the optimum design of medium and high frequency transformers.

Key words： Iron loss magnetostriction amorphous alloy loss model
