Abstract:
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.
