Description
Summary:State-of-the-art high-power applications offer a high level of complexity, containing, e.g., linear, hybrid and nonlinear elements. The development of advanced control algorithms requires enhanced simulation effort featuring hybrid systems containing continuous and discrete elements. Besides a brief description of a simulation concept fulfilling these requirements and additionally minimising development time losses by program portation using an interface for control algorithms implemented in C, the use of Petri Nets for the modelling of the switching elements is introduced. A Petri-Net representation of a 3-level NPC inverter is derived. The capability and accuracy of the chosen simulation approach is outlined by simulation results of a 3-level-NPC-inverter feeding an IM, represented by a R-L impedance and EMF.
