High-Frequency Modeling of Electrical Drive Systems Considering Test Bench Environment Influence
IEEE Transactions on Power Electronics, vol. 40, pp. 12816–12828
Abstract
This study addresses the challenges of highfrequency modeling in electrical drive systems, particularly considering the influence of the test bench environment. A universal grey-box modeling approach is developed to accurately represent the frequency-dependent behaviors of Permanent Magnet Synchronous Machines (PMSMs) and cable sets up to 10 MHz. The proposed method integrates impedance measurements and parameterization to model complex effects such as the skin effect, proximity effect, and parasitic capacitance. The influence of the test bench environment, particularly on the cable set's layout and electromagnetic interference from the test bench, is systematically analyzed and incorporated into the model. Validation results in both frequency and time domains demonstrate a significant improvement in model accuracy. This work provides a robust framework for high-frequency modeling, enhancing the design and optimization of insulation systems and the prediction of transient behaviors in electric drives.
