Advanced preprocessing and correction-methods for automated generation of FPGA-based simulation of power electronics

Power electronic devices are important in almost all industrial sectors. Power converters are used for electric drive systems in the production of an automation industry, in the automotive industry, as power supplies in telecommunications or for power conversion in power supply systems. For testing such electronic equipment, hardware-in-the-loop simulation is almost a standard method today, especially in the automotive industry, which always requires a real-time simulation of the plant. For testing the electronic control units of power electronics, real-time capable models of power electronic circuits need to be developed, accordingly. In the previously published contribution [10] different modeling methods were described and an algorithm was developed, which can be used to simulate power electronic circuits in real-time. Based on this algorithm and the automated generation of such models ([10]), further improvements for reducing the memory usage, increasing the degree of parallelization and improving accuracy are described in this paper. However, the presented approaches and modifications as well as the studies on correction methods for switching events and the preprocessing can be applied to other algorithms.
