“…For highquality welding an efficient controller becomes imminent to ensure high current at a short duration. The fact that self-tuned Fuzzy PI controller exhibits superior dynamic characteristics in comparison with intelligent controller and FUZZY controller (Wang et al, 2018;Sarvi et al, 2014), validates its choice for the proposed power source.…”

Purpose The purpose of this paper is the attempt to model a variable speed permanent magnet synchronous generator (PMSG) for extracting a standalone power source to assuage the needs of a welding application. The emphasis orients to evolve a framework for the effective exploration of renewable energy resource and prevent the injection of grid harmonics. Design/methodology/approach The system involves the use of self-commutated dc-dc converter interfaces to extradite the current and voltage requirements of the welding attributes. The philosophy incites a pulse width formulation for reducing the voltage ripples in the dc output and improving the time response characteristics. Findings The proper selection of closed loop Fuzzy tuned PI control ensures the restriction on the magnitude of the current drawn from the source, enhances the dynamic response and betters steady state response. Originality/value PMSG-based welding power source with parallel-connected cascaded buck fed cuk converters. MATLAB-based simulation of the methodology offer interesting results in the sense it orchestrates the range of converter operation and the ability to provide a high-quality weld without polluting the ac mains. The experimental prototype further proliferates to validate the simulated performance and claims a space for its use in the real-world utilities.

“…Managing an Micro Grid through a large number of Distributing Generations, variable loads, and ESA is challenging, especially given the high degree of renewable energy (REG) generating penetration. To highlight the high use of efficiency power, the REG is generally arranged using maximum power tracking (MPPT) algorithms [7][8][9][10]. As a result of the fluctuating and uncontrolled meteorological circumstances, it is classified as a generation that cannot be regulated [11][12][13][14][15].…”

This research looks at how photovoltaic (PV) cells generate energy in different weather conditions. Photovoltaic power today plays a key role in the production of energy and satisfying the needs of consumers all over the world. The PV cell's ability to generate electricity was entirely dependent on sunshine and temperature fluctuations in the environment. Several researchers are working on a variety of MPPT methods for a photovoltaic system. Outdated MPPT techniques are unable to withstand a dramatic change in weather conditions. The fundamental purpose of this study is to associate the numerous unadventurous and clever controllers for MPPT of the PV system, such as the PSO, GA, and CNFF. The MATLAB environment was used to create and simulate the recommended intelligent controller for MPPT in the PV system. Furthermore, the aforementioned findings like Voltage, Current and Power with respect to different irradiance and temperature are compared and evaluated. The performance of the above-mentioned topologies has been related to the optimum intelligent controller for the PV system and cncluded that the CFFNN gives better efficiency with minimum time required to extract.

El presente artículo documenta el diseño e implementación de un controlador robusto para el convertidor CD/CD Reductor–Paralelo, bajo la perspectiva de la planitud diferencial y la técnica del control por rechazo activo de perturbaciones basado en un observador GPI. Los objetivos principales del controlador propuesto son: regular la tensión de salida y equilibrar las corrientes de los convertidores en paralelo. Para el modelado de la arquitectura hardware de este controlador se utiliza una herramienta con alto nivel de abstracción de hardware y se implementa en un FPGA Artix–7 de la compañía Xilinx. Finalmente, se muestran resultados experimentales del desempeño del controlador, cuando se somete al convertidor a diversas perturbaciones externas, desconocidas y variantes con el tiempo, y a cambios en los parámetros del mismo.
