Analysis and control of PWM converter with V-I output characteristics of solar cell

In this paper, the virtual implementation of a solar cell (VISC) was proposed to solve problems such as the reappearance and repetition of situations in photovoltaic power system experiments, and to achieve reliable experimental results on PV power systems. VISC emulates the solar cell output characteristics, and can substitute for solar cells in laboratory experiment systems. To realize the VISC, a mathematical model of solar cell for the driving power converter was studied and the buck and buck-boost power converters were compared from the viewpoint of the tracking error of the characteristic curve of solar cells using computer simulation.
