Introduces Ansoft electromagnetic field simulation software Maxwell2D/3D for the modeling and simulation of ZTSG-530 / 6 phase-shifting rectifier transformer and makes simulation analysis of the no-load characteristics of the transformer. The results tallies with the values of experiments and design. At the same time in accordance with the structure of primary winding and secondary side and the change of load parameters in the transient field, analyses the forces of the coil under the no-load and short-circuit. Through the simulation analysis, the result provides a certain theoretical reference to improve the performance of the transformer.
