Research on Model of Buck-Boost Converter Based on Digital Twin

Digital twin could be regarded as a virtual model, presenting the features of physical entity. Through interacting with the data of the actual world, digital twin could timely adjust its parameters and accurately simulate the running characteristics of a physical entity. Mathematical model is an important part of digital twin model. Buck-Boost converter is an important converter circuit, which has been widely used in many fields due to its excellent characteristics. In this paper, Buck-Boost converter is taken as a research entity, analyzing and studying its digital twin model. Firstly, the mathematical model of Buck-boost converter is built based on its circuit topology. Secondly, a numerical solution of the mathematical model could be calculated through the fourth order Runge-Kutta algorithm. In the end, the digital twin model of Buck-Boost converter is built. Then its simulation model is built in MATLAB, which shows the model is accurate.
