“…By increasing the magnetic flux density and reducing the leakage inductance of the TR, efficiency improvement and volume reduction can be achieved. However, the conventional TR has been optimised almost fully [7][8][9][10][11][12]. Hence, it will be difficult to improve the efficiency or reduce the volume of a conventional TR, significantly, which in turn makes it difficult to optimise a converter using the conventional TR.…”

Recently, power conversion systems (PCSs) have exhibited high efficiencies and miniaturisation, and this trend is expected to grow in the future. An important component of the PCS, which accounts for a significant portion of its volume, is the transformer (TR). However, it is difficult to achieve a significant increase in the efficiency and reduction in the volume of a PCS using a conventional TR, as the conventional TRs do not offer much scope for further optimisation. To overcome this limitation imposed by the conventional TRs, a novel and practical high-frequency coaxial TR, named the shell-type coaxial TR (SCTR), is proposed in this work. A useful and strategic analysis and design method, which covers the overall development process from the design stage to the experimental validation stage of the proposed high-frequency SCTR, is also proposed. The usefulness of the proposed SCTR and the analysis and design method are verified by designing an SCTR for a 50 W DC/DC converter and conducting experiments on it. It is found that the use of the proposed technique can cause a significant increase in the efficiency and power density of the PCS

The climate's dependence requires a complex modelling and other optimization methods for the control of the hybrid system. Moreover, recently, and as for both the technological progression of the hardware and software, researchers may more and more optimize problems through the use of enabled platforms. The paper aims to discuss this issue. Our hybrid pumping installation contains a photovoltaic generator, a wind source, converters, and an induction motor‐pump group; it has a hybrid and complex character and requires a good modelling of the energetic point of view before passing the phase of design of control laws. So we use the graphical approach of modelling called dedicated graph for this type of system, and this tool showed very interesting results in the level of modelling, dimensioning, monitoring, and diagnosing. The numerical closed‐loop simulation of the complete model in an appropriate environment allows us to generate an optimization control in which the appropriate frequency depends on meteorological conditions. The simulations are made from the climatic conditions measured in a real system using a microcontroller ARDUINO board. These measurements are used to simulate the adopted control and to judge on the feasibility of our architecture adopted.

“…The maximum power operation has been achieved by interchanging the series parallel connections of solar cell modules within the photovoltaic array [9]. Also, the maximum power tracking has been achieved by using controlled dc-dc converters [10][11][12]. Experimental implementation of fuzzy logic control for photovoltaic maximum power tracking is given in reference [13].…”

This paper presents theoretical and experimental analysis of the performance of a photovoltaic system supplying DC loads and controlled by either a cuk or a sepic converter. The nonlinear mathematical model of the system is obtained, considering all operation modes of both converters. A fairly detailed nonlinear simulation was built to assess the performance when system is supplying constant and dynamic loads. Simulation and experimental results are presented illustrating both the steady state and the starting characteristics of the system. The relation between solar irradiation level and the duty ratio for both steady-state and run-up for the cuk and sepic converters have also been given to ensure maximum energy utilization. The results are presented in a comparative form which clearly illustrates that the cuk converter operates over a wider range of irradiation levels. The results also show that with a proper design of photovoltaic generator and careful selection of the dc-dc converter, the performance of a particular application can be optimized by controlling the converter duty ratio.
