An Approach for Accurate Designing of Transformers Supplying DC Load Currents

M. Sedighizadeh and M. Khatibi

Abstract—Transformers which supply DC load currents— known as rectifier transformers—face with harmonic problems as the rectifier circuits connected to their secondary windings are based on semiconductor devices and thus, generate harmonic currents. Accurate designing of such transformers highly depends on these harmonic currents. The typical method employed to design these transformers is often time consuming and there is a high risk of various mistakes since it is hardly possible to model the transformer and the rectifier together during the design process. In this paper, an approach is developed for accurate designing of transformers which supply DC load currents. In the proposed approach, a database including 11 types of rectifier circuits, employed a lot for industrial purposes, as well as their harmonic analysis is created by means of computer simulations. Next, the transformer and the selected rectifier are simulated together and the harmonic spectrums existing in individual windings of the transformer are extracted. Finally, transformer parameters are designed based on the extracted harmonic spectrums and their resulting effects. The results of applying the proposed approach to an example of IEEE Standard No.C57.18.10.1998 for semiconductor power rectifier transformers evidently verifies the usefulness of the presented approach.

Index Terms—Dc load currents, design, harmonic spectrums, rectifier transformer.
