Abstract This paper researches the phase-shifting rectifier transformer(PSRT), which is characterized with its complex winding structure such as axial splitting and parallel branch. Firstly, the 3D analysis model of leakage magnetic field and corresponding equivalent electric-circuit are established by utilizing FEM coupled with equivalent circuit method. Under the asymmetric operating condition, the electromagnetic parameters such as magnetic leakage field in the windings, distribution of branch current, and short-circuit impedances, are calculated and verified. Therefore, the distribution regularity of current in the windings is obtained from the calculation results. On this basis, the finite element simplified model is built and corresponding calculation software is developed for PSRT. Finally, through the comparison with experimental data or 3D calculation result, it is shown that the distribution of magnetic leakage field is correct, and the analysis results of short-circuit impedances can satisfy the requirement of product performance using the given engineering method or software. Thus, the convenient and reliable engineering analysis method is supplied for the design of PSRT.

Key words： PSRT asymmetric operation magnetic leakage field electromagnetic parameters engineering method
