文档介绍：Abstract
In recent years, with the rapid development of global electronic information industry, DC-DC switching converter is widely used in the areas of the national defense and civilian electronic industry. So the study of DC - DC switching converter is one of the core research content in the field of power electronics. However, because the DC-DC switching converter is a strongly nonlinear system and the study of the modeling method is a plex difficulty. Although domestic and foreign scholars has obtained certain research results in the modeling method of DC - DC switching converter, but most of them have certain limitation which people often ignore , it is easy to cause the analysis not accurate. So it is necessary to conduct the thorough research to the limitations monly used modeling methods, and explore new train of thought of modeling method.
Firstly, using state space average method and three terminal switching device model method, time average of equivalent circuit model respectively for the Boost converter working in continuous current mode (CCM). The mathematical model of three ways is consistent with each other, and the simulation results and the actual circuit working under different frequencies of the results pared. Then the limitations of traditional ideal switch converter modeling method of specific performance.
Then, in order to verify the impact of the tradi
