In this paper, a voltage regulation system is proposed for photovoltaic energy sources (PV), using Single-Ended Primary Inductance Converter as a DC-DC converter to feed loads working with specific input voltage. The choose of SEPIC converter is due to the output voltage ripple of developed-type converters are usually small and can be lower than 2%, also it considered as a buck and boost converter and thereafter loads with lower or higher voltage could be powered. Matlab Simulink is used as

Two algorithms are used to fulfill this role: A Conventional PID and PI-Fuzzy logic controller to generate the PWM signal for the SEPIC converter. Hence, to validate the work some real-time simulations are treated by implemented the control strategies on a low-cost control board: The Raspberry Pi 3 in order to manage the operation of system and collecting the simulation data. Also, and for verification purposes, several simulations were treated to verify the good behavior of the proposed system.
