Abstract :
Maximum power point tracking(MPPT) is very important in relation to solar energy development. Currently, there are two problems facing the existing MPPT methods namely the tradeoff between the steady-state oscillations and dynamic behavior, and then the tradeoff between high computational load and accuracy. The Beta method can address these two problems since it shows a fast tracking speed in the transient stage, smaller oscillations in the steady-state and medium complexity of implementation. However, for optimal performance, it is essential to identify the configuration of the parameters with regard to the Beta method. Therefore, paper will examine the different performance level with the different values of the parameters, and then will provide an optimum example. In order to verify this procedure, a boost converter was proposed in MatLab/Simulink for simulation. Finally, an experimental prototype was constructed with a solar array emulator and DSPACE.
