### Abstract

This paper adopts the method of combining impedance test and simulation to model the high frequency characteristics of series diode array. Firstly, the high frequency equivalent circuit model of series diode array is established and its impedance calculation method is explained; then use the vector network analyzer (VNA) to complete the impedance test of series diode array, and use the differential evolution algorithm (DE Algorithm) to fit and optimize the high frequency model parameters; finally The characteristics of the ideal diode and this high frequency model are compared under different frequency, and the PFC circuit simulation verification is carried out in ANSYS software. The results show that this high frequency model not only matches the characteristics of ideal diodes at low frequencies, but also reflects the high frequency characteristics of series diode arrays that are different from ideal diodes at high frequencies. The modeling effect is excellent.
