Abstract

It is significant to calculate the load loss of the converter transformer for operating steadily. In this paper, several methods for calculating the load loss of the converter transformer have been compared and discussed. Then the assumed conditions for methods are analysed. It is indicated that the stray loss in structural parts is proportional to the square of the current approximately, but it is necessary to test whether it follows the frequency with the exponent 0.8, otherwise the method will cause the error for the load loss calculation. It is advised to analysis the non-magnetic material and magnetic material separately.
