The battery’s DC voltage has a high voltage ripple, and therefore does not apply to most devices. DC converters are used in the voltage to relieve ripples regardless of the change in load voltage. In this paper, a design and implementation of positive output super lift POSL LUO converter using maximum power point tracking (MPPT) Algorithm in photovoltaic (PV) system. In LUO converter is highly efficient with low ripple in current and voltage. The super lift converter is a developer converter that comes from the buck boost converter, it is considered of the best converters. Used for low voltage irregular in photovoltaic to a higher voltage without ripples or voltage step down according to the design of the converter, it therefore applies to most devices, such as electric vehicles, dc-chargers, etc. The efficiency of the panels can be improved using maximum power point tracking algorithm, among the many accessible MPPT methods, perturb and observe method. The proposed P&O method based on the PI controller gives the best duty cycle, to eliminate the oscillations in the converter output value, and extracts the highest energy from the PV system. The values of the PI controller are adapted by trial and error method. The results were confirmed using MATLAB / Simulink in DC-DC converter design with MPPT.
