A multilanguage environment for interactive simulation and development controls for power electronics

Virtual prototyping of complex systems presents interesting challenges, especially with regard to systems in which different languages are used to represent different parts. We describe here one approach to solving such a problem. In particular, we describe how to integrate the virtual test bed (VTB) solver engine with the Simulink solver. This produces a rich environment for virtual prototyping of power electronic applications due to the inherent mixture of circuital and control problems. The integration is conducted within the context of the resistive companion approach. We present here the theoretical foundation of the approach, and also suggest the generality and extensibility to other solver engines such as SPICE. The theory is then enriched with some examples that illustrate the approach including the use of the VTB high-level graphic user interface.
