【 摘 要 】
Solar energy, a renewable energy source, occupies an important position in energy generation. While it is environment-friendly, silent and non-fuelled, its high investment costs and inconsistent efficiency in terms of energy conversion pose various disadvantages. Therefore, studies on the improvement of systems operated via photovoltaic energy gained importance and the researches and developments within the field of current power conversion systems enabled the photovoltaic systems to gain momentum. Maximum power point tracking (MPPT) must be used in order to obtain maximum performance from solar energy systems. In this study, perturb and observe (P&O) algorithm, the most commonly used algorithm in MPPT systems, was analyzed, an approach towards eliminating oscillation problems, improving speed andto obtain more power value , were maintained and reference current value obtained from P&O algorithm under changing and constant PV panel radiation conditions was driven by a DC / DC boost converter that can be used in charging structures. Finally, it was evaluated along with simulation results.
