Modeling and Simulation for Boost Converter Based on HDS Theory

As a typical power electronic circuit, the dynamic model of boost converter can be viewed as a mixing or interacting system between the discrete event and continuous time variable, also known as hybrid dynamic systems. By using of hybrid dynamic systems theory, a hybrid model of boost converter was established and simulation was carried out to verify the validity of the method in the MATLAB. Compared with traditional state-space averaging method, a more accurate model of boost converter was obtained without treatment of approximate linearization based on hybrid dynamic theory.
