Analysis of modeling and simulation of Buck-boost converter considering dynamic phasor method

摘要

With flexible AC transmission systems (FACTS) technology becoming more and more mature, flexibility, controllability and stability of modern power system has been greatly strengthened. At the same time, the traditional sinusoidal steady state or quasi-steady-state analysis methods become difficult to meet the requirements on both speed and accuracy of power system transient problems. This article applies the dynamic phasor method to Buck-boost converter modeling and simulation. Simulation results show that the model calculation speed is faster, and it can accurately reflect the dynamic characteristics of the converter.
