In this paper, using the proposed converter modeling and presenting a proposed control scheme, the maximum power point tracking (MPPT) is developed to lead to its optimization. The photovoltaic energy conversion system generates energy with the help of a step-up interleaved DC-DC converter. In photovoltaic systems, controllers are commonly used to manage the power injected into the grid or load. MPPT is one of the features that some of these controllers are equipped to it and increase power efficiency by up to 30 compared to conventional controllers. In fact, the main purpose of this study is to improve the incremental conductance (InC) algorithm by the state-space averaged model and PI controller. The signals generated in the closed-loop control scheme, including input and output currents and voltages, are accurate and have very low ripples. Experimental results were analyzed using Arduino Due and the effective performance of the proposed control scheme was verified on the proposed DC-DC converter
