Abstract

Abstract: The analytical calculation method for winding loss and core loss of high power medium frequency transformer was analyzed, and the optimal design process was established. A 300 kW medium frequency transformer for lightweight application of electric locomotive was designed optimally by the method of free parameters scanning. Through the establishment of evaluation parameters equation, the best scheme considered both the total loss and transformer weight. On this basis, the winding loss and core loss for six groups of design scheme were verified by finite element simulation in 2D eddy current field and transient field of Ansoft Maxwell respectively. Through the results comparison of analytical design and finite element simulation, the error is acceptable, which verifies the correctness and effectiveness of the optimal design method.

Key words: high power medium frequency transformer, optimal design, lightweight, high frequency loss, finite element simulation
