Abstract-Despite the advantages of photovoltaic (PV) modules such as noiseless operation, being fuel-free and non-polluting, the most important factors hindering their wide use are high investment costs and low energy conversion efficiencies. By reason of that, studies involving efficiency improvement of the systems fed by PV energy is deemed important. In recent years, studies about PVs have focused on minimize the costs and maximize the conversion efficiency. In order to maximize the efficiency of PV energy conversion systems, solar panels and arrays should be operated at maximum power points (MPP). At MPP, solar arrays generate the electric energy at maximum efficiency and minimum losses. Solar cells have variable current and voltage characteristics and MPP depends on solar irradiations and ambient temperature. So a maximum power tracking control should be made rapidly in different temperature and solar radiation conditions. In this study; solar cell was obtained by using equivalent circuit of solar cell with Matlab / Simulink and by using this structure , a PV generator was designed which is not only used with boost dc / dc convertor but also used with MPPT (maximum power point tracking) unit. Besides due to its easy implementation, P&O (Perturb-Observe) which is the most common algorithm in PV systems is originally modified for oscillation problem and chosen the design of the MPPT. Finally, wireless energy transmission was applied in conventional and using MPPT PV system on experimental setup for comparing.Index Terms-DC / DC converter, MPPT, P&O algorithm, PV panel, wireless energy transmission.

Summary A new multiphase quadrupler with interleaving technique for high power photovoltaic interface applications is proposed. The designed converter fuses the features of interleaving technique and high gain quadrupler converter producing low voltage stress with reduced ripples. Detailed theoretical analyses for each mode of operation through design equations are derived. The results are analysed and compared with conventional high gain quadrupler circuits. The simulation and experimental results have proved that the converter produces an extremely high voltage gain with low duty ratio. The proposed nonisolated topology achieves zero voltage switching (ZVS) with no additional circuitry. It is also verified that the ripple in the input and the output sides are less such that it can be well suited to interface with PV source. The switching losses and the conduction losses are considerably reduced, thereby giving an efficiency of 97.7%. The proposed converter is tested for a power rating of 790 W.

“…A linear equivalent electrical circuit of PV module has been proposed in Theocharis and Pyrgioti for implementing on EMTP platform. Pandiarajan et al have developed power electronic circuit oriented model of PV module, and its results are experimentally validated. It is worth mentioning that the above models involve iterative solution due to algebraic loop, where the performance of these models depends on the algebraic loop solver on SIMULINK/RTDS (Real Time Digital Simulator) platform.…”

Summary The solar power plants are playing a significant role in energy market due to its eco‐friendly nature, low operational, and maintenance cost. The efficiency of these plants depends mainly on load impedance, topology of converters, and maximum power point tracking algorithms. In this work, effect of operating point (load line selection) on the performance of maximum power point tracking for different DC‐DC converter topologies has been studied and experimentally validated. Further, the operating constraints of buck, boost, and buck‐boost modes of converter operation in terms of load impedance are presented. The performance of different maximum power point tracking algorithms under load and solar irradiance change has been investigated for all converter topologies discussed. The modified model of photovoltaic module has been presented for simulation study under different solar irradiance and load variations that can be easily implemented on Real Time Digital Simulator platform unlike conventional models.
