A Complete Mathematical Modeling, Simulation and Computational Implementation of Boost Converter Via MATLAB/Simulink

Abstract

This paper describes mathematical modeling techniques, simulation and implementation of boost converter. Four modeling techniques such as circuit modeling, mathematical circuitry modeling, and transfer function modeling and state-space modeling. Each modeling method is developed and implemented in MATLAB and Simulink environment. Circuit modelling is also done in PSIM tool. From the simulation results it is clear that capacitor voltage waveform which is a state variable gives identical response in all modeling techniques; state-space, mathematical circuitry, circuit and transfer function modeling approaches. Simulation results of all models perfectly overlapping each other and also settling time is very less in circuit modeling and transfer function modeling which is more desirable .Stability analysis ;bode plot ,pole-zero plot and step response are carried out using transfer function modeling .The offered models helps to the expansion of boost converter design, simulation ,analysis and educational tool[1].
