    Abstract
    This paper examines the winding losses characteristic of a 4 kVA high frequency coaxial transformer used in the bi-directional DC-DC converters. With consideration of nonlinear behavior of the magnetic material, the winding losses of the transformer can now be estimated more accurately. Three-dimensional (3-D) simulation techniques, in conjunction with the Finite Element Method (FEM) technique, were deployed. These techniques significantly improve the calculation accuracy of the winding resistance under any specific condition. Prototypes were built to validate the effectiveness of the simulation and computation results. The ...

    This paper examines the winding losses characteristic of a 4 kVA high frequency coaxial transformer used in the bi-directional DC-DC converters. With consideration of nonlinear behavior of the magnetic material, the winding losses of the transformer can now be estimated more accurately. Three-dimensional (3-D) simulation techniques, in conjunction with the Finite Element Method (FEM) technique, were deployed. These techniques significantly improve the calculation accuracy of the winding resistance under any specific condition. Prototypes were built to validate the effectiveness of the simulation and computation results. The simulation result and the measurement result are consistent with less than 10% error.
