Modeling the terminal behavior of power system components in transient condition is of great necessity for systemlevel simulations of future DC grids. One vital component in DC grids are power electronic converters. Therefore, efficient models of power electronic converters, which model their terminal behavior, are needed for transient system-level simulations. In this paper, an approach for eliminating...
In this work the spatial electro-thermal modeling of power electronic modules is discussed. It is shown how physical and mathematical modeling techniques can be combined to obtain a compact time efficient electro-thermal simulation framework for power electronic modules. The framework can be used to evaluate the transient temperature distribution of a power module in an electric vehicle over driving...
For high power converter designs, a performance screening with hundreds or thousands of configuration combinations and operation points is typically required. Standard time-domain based circuit simulators are not efficient for such screening works because of the long computation time. In this paper, a modeling and simulation methodology is presented, which is ultra-fast compared to time-domain based...
A universal and modular approach for synthesizing electromagnetically excited vibrations in electrical machines is presented. The synthesis process uses force responses, i.e., the normalized structural vibration responses for a machine's generic set of force excitation shapes. The responses are superposed after scaling by the operating point dependent force excitation amplitudes. This leads to a computationally...
