Modeling and Simulation of DC-DC Converters

Abstract

DC-DC converters are used in many types industrial applications. They are used to change the DC source voltage level to higher or lower level. In recent years, as the use of photovoltaic systems increases, DC-DC converters have got more important. In this study, the basic DC-DC converters, named boost, buck and buck-boost converters, are modeled and simulated in Matlab/Simulink. The detailed circuit equations and derived models from that equations for each switching modes are presented in the study. The obtained results from converter models are verified with electrical simulations that is utilized Simulink blocks. Closed-loop control is used in both methods. Both simulations are realized in the same conditions, such as controller parameters, circuit parameters and simulation options in Simulink. Transient-state with load change and steady-state response of both methods are compared in the study. The output voltages of each methods and difference waveforms are given in the results. They show that the presented models can be used for simulation of these converters.
