Abstract : In present occasions, sustainable sources of energy are increasingly valued worldwide because of energy shortage and environmental contamination. High step-up DC/DC converters are broadly utilized in sustainable power source applications, including photovoltaic frameworks. To satisfy the expanding power need, usage of the accessible vitality (Renewable vitality) is the promising answer for it. Solar Photovoltaic based Parallel Single Ended Primary Inductance Converter (SEPIC) fed resistive load and PMDC motor can be designed to obtain the desired voltage. SEPIC converter suitable for the PV applications, here the focus is made on a simple and cost-effective converter for the open-loop and closed-loop control design the SEPIC converter is capable of extracting PV power while extracting the available power from the PV source, which ensures the effective utilization of the renewable source. The circuit used Parallel based topology. To achieve high current ratings and reduce the ripple, the SEPIC converter is suggested. The simulation will be done with R load as well as with a PMDC motor. The simulation work of the Parallel SEPIC converter fed R load and PMDC motor circuits with an open and closed loop with PI control has been done using MATLAB software. Thus, voltage ripples are reduced and efficiency can be improved when compared with the conventional buck-boost converter. PI controller is used for the closed-loop system. A microcontroller used to generate pulses for controlling the SEPIC converter implemented in hardware.
