A Hard- and Software Co-simulation Model of a Matrix Converter

In recent years the simulation tools have been optimized for precise modelling and simulation for their special purpose. Therefore the simulation tools have been developed to model and simulate a certain problem. In the past, the hardware was used to be modeled in a SPICE simulator, the software in a signal and differential equation based simulator. Nowadays the investigated systems are decreasingly only software or only hardware but a complex system architecture of hard- and software interlinked with each other. Therefore the interfaces of hard- and software can not always be simplified to a simple mathematical function as an initial precondition for isolated simulation of hard- and software. Due to the absent ability of simplifying the interfaces, a Co-simulation of hard- and software has to be performed. In this paper a holistic model of an matrix converter is presented, modelling power electronics in PSPICE and commutating logic as well as software in MATLAB/Simulink.
