Abstract

The Dymola modeling language has been shown to be useful for modeling electrical networks in an object-oriented manner. The ability of Dymola to handle time and state events in an object-oriented manner also makes it particularly suitable for modeling switching power converters, whose models may generate thousands of events over a simulation run.

The object-oriented nature of Dymola is well suited for modeling complex power supply systems. Circuit designers may develop and test their converter models; systems designers may use these as building blocks in larger systems without needing detailed knowledge of the converter models. This is demonstrated by means of an example wherein a complete converter system is developed beginning from the component level.
