This paper presents a 2-D nonlinear finite element analysis (FEA) tool embedded in Matlab/Simulink surrounding for the application of electromagnetic field analysis in power converters. Comparing with other FEA tools such as ANSYS and ANSOFT, as different control arithmetic has been realized in Matlab/Simulink surrounding, the significant advance by using the FEA tool embedded in Matlab/Simulink surrounding is that the field analysis can be more easily interfaced with the external control arithmetic. Considering that the characteristics of most field analyses in power converters which are static electromagnetic equipments, not only the general application procedure of the 2-D FEA tool is introduced, but also some improvements for strengthening its function is proposed As an example, the proposed model is implemented for the performance analysis of a flyback switching AC-DC converter. By running the proposed model in Simulink surrounding, several performances can be obtained efficiently.
