Average model simulation of dc-dc boost converter for solar energy system applications with perturbation and observation algorithm

Abstract The primary use of boost converter is set in power supplies of direct current and is the productive brake of direct current motors. So that its name implies, the output voltage is always greater than the input voltage. When the key is attached, the diode bias is reverse and separates the output class and leads the input energy to the inductor. When the key is off; it receives the energy output class from the inductor and input. To control running the converter of the direct current to direct, we need a good model from converter that the model is provided under two important cases of average mode equations which are the voltage of the capacitor and the inductor current. In this paper, dynamic modeling of the boost converter is done in the application of solar energy system and then related algorithms are presented. To verify the findings of theory, simulation is done with Matlab software and Simulink. Simulation in Matlab and Simulink indicates changes of two important cases of average mode equations that are the voltage of capacitor and the inductor current.
