Multilevel modeling and simulation of power electronic systems

The author introduces the CASPOC program for multilevel modeling and simulation of electric circuits and dynamic block diagrams. Because of the multilevel approach it is possible to model the power converter, electric components and the control on different levels. These levels are combined into one multilevel model. It combines the advantages of modeling with circuit elements, dynamic nonlinear system blocks and modeling language. Using the program one can model power electronic converters and electric machines. One can also model analog or digital control, for example vector or fuzzy control, enabling the complete multilevel modeling and simulation of drive systems.<>
