Abstract:
This paper studies the high-frequency model of the toroidal inductor coil based on the evolutionary difference algorithm. Firstly,an equivalent model of the toroidal inductor coil is established,and the calculation method of its impedance is described. Then,the amplitude-frequency characteristic curve of the test coil is obtained through the VNA device,and the evolutionary differential optimization The algorithm optimizes the equivalent model parameters to obtain the optimal model parameters,and compares the impedance fitting curve with the measured curve through simulation. The fitting effect is good,and the reliability of the model and parameters is verified. Finally,the inductance coil is added to the simulation of the switching power supply radiated EMI,and its effect of suppressing electromagnetic noise is verified,which provides a theoretical basis for the actual engineering rectification.
