In this paper, we present an intelligent algorithm based upon Fuzzy Logic method for optimizing and improving the control performance of a photovoltaic system. The main objective of the proposed system is to pursuit the maximum power point (MPPT) under different conditions like the change of sunshine and temperature. The system consists of a photovoltaic solar module connected to a DC-DC step-up converter "Boost" and a battery - like a load . The converter parameters and the inference rule table are determined to ensure maximum output power. The effectiveness of the proposed system is validated through computer simulations using MATLAB / Simulink software and the obtained results shows that our proposed system has the best performance in term maximum power.

“…Once the power switch is off, the load stage gets energy from the inductor as well as from the source, therefore the load voltage is greater than the source voltage. Conventional boost converter has a simple circuit and low cost [8]. The disadvantages of conventional boost converter are high ripple current on active and passive components, large voltage stress for power switches, and require a large capacitor value to keep the output voltage steady [9].…”

DC-DC boost power converters play an important role in solar power systems; they step up the input voltage of a solar array for a given set of conditions. This paper presents an overview of the variance boost converter topologies. Each boost converter is evaluated on its capability to operate efficient, size, and cost of implementation. Conventional boost converter and interleaved boost converter are widely used topologies in photovoltaic systems reported; however, they have negative sides of varied efficiency level under changed weather conditions. Therefore, this paper proposes, interleaved boost converter with novel switch adaptive control, to maximise efficiency of standalone photovoltaic system under change of solar power levels, due to illadation condition.

“…Interleaved boost converter that operates at light-load or in the range between 20% to 40% of maximum power, the inductor current becomes smaller due to the doubling of the inductor number, thus forcing the converter to operate in a discontinuous conduction mode. Interleaved boost converter operating in DCM mode will cause large peak currents and high current stress causing losses in power components that lead to poor efficiency [9]. This paper presents design and analysis of 250 W boost converter that combined with an automatic operation region switch in the form of interleaved and non-interleaved operation region selector circuit to avoid discontinuous conduction mode when operating under light-load condition or 20% to 40% of maximum power.…”

Interleaved boost converter gives good conversion efficiency due to its zero-current switching capability when operating in discontinuous conduction mode while keeping its input-output ripple current low. However, operating this kind of converter at interleaved operation for all the time gives poor efficiency under light-load condition. In this paper, an automatic operation region selector switch based on detection of the continuous or discontinuous current mode is proposed. With this switch, during the light-load condition, only one converter is activated, while during full-load condition both converters will be activated. The simulation results using LTspice software show that the proposed boost converter has a better efficiency compared to the conventional boost converter with efficiency range of 84.6 % to 95.32 % under various load conditions.
