The 3D calculation model of FEM coupling with the equivalent electric-circuit (EEC) is established for a test transformer of several parallel coils. Numerical analyses of 3D magnetic fields and branch currents, etc. in coils are carried out by using field-circuit coupling method (FCCM). The validity of the calculated results is verified by comparing with measured value of test transformer and some distribution rules of electromagnetic characteristics are given for design of high current transformer.
