N2 - Models of power electronics systems are the basis for further analysis and control, so the vector fitting, a widely used data-driven modeling approach, becomes par-ticularly important. However, vector fitting often requires a large number of frequency response measurement points, otherwise it may converge to an inaccurate model. To address this issue, this paper uses the sampling optimized method to obtain a more reasonable distribution of measure-ment points before vector fitting. This paper demonstrates that combining these two methods can effectively improve the accuracy of the fitted model. Numerical tests prove its effectiveness.
