Abstract：As one of the most important performance of the power supply, winding loss has attracted much attention. Its research methods mainly include theoretical analysis, simulation analysis and measuring analysis, but because of the limitation and low precision of the theoretical analysis, and the huge work and large cost of time of the measuring analysis, the simulation analysis has become the first choice. The memory requirement is too high and time-consuming is too large of traditional 3D simulation model, and as a replacement, the single-2D simulation model has a big error because it’s unable to fully describe the magnetic field distribution of actual magnetic component. In this paper, the quasi-3D model was proposed to avoid the above shortcomings by the analysis of flux path in actual magnetic component, and the validation of the accuracy has been completed through various loss simulation of kinds of models.
