Combining various modeling techniques for power electronic systems in automotive applications

Rapidly increasing complexity of electrical designs in automotive applications leads to growing role of system level modeling and simulation techniques in the design verification. This kind of verification requires integration of models describing system behavior at various fidelity levels: from behavioral control blocks to single device electrical models. Growing interest in power electronics applications due to hybrid vehicles developments has become another challenge for modeling and simulation engineers. This papers describes combination of various modeling techniques - from state diagrams to transistor level modeling - which allow time efficient and accurate representation of both steady-state and transient response (including self-heating effects) of a complex power electronics system in automotive applications.
