Multi-resolution switched system modeling

Abstract

An approach for simulating linear switched networks, such as certain models of power converters, is given. The approach applies the principle of multi-resolution simulation. A full, detailed model is constructed from which a reduced order model is automatically extracted. The bandwidth of the reduced order model can be specified and changed at the users' discretion, even during a simulation run, yielding multiple resolutions and simulation speeds. The method is demonstrated on a simple power converter circuit.
