“…However, the real issue is that an excessive number of dynamic switches are available, and the utilization of transformers makes the structure massive [14,15]. The non-isolated structure does not utilize a transformer which makes for an economical and simpler structure [16][17][18][19][20].…”

Abstract:A non-isolated Multiport Single Ended Primary Inductor Converter (SEPIC) for coordinating photovoltaic sources is developed in this paper. The proposed multiport converter topologies comprise a Single Input Multi yield (SIMO) and Multi Input Multi Output (MIMO). It is having the merits of decreased number of parts and high power density. Steady state analysis verifies the improved situation of both the proposed topologies, which is further checked through simulation results.Keywords: single input multi output; multi input multi output; single ended primary inductor converter

“…The three-port DC-DC converter used to interface PV source, battery and the load is obtained by combining two SEPIC/ZETA bidirectional converters in parallel and by fusing with the fullbridge converter (Wu, Xu, Hu, Zhou, & Xing, 2014). This converter is capable of operating in three different operational modes depending upon the availability of PV source.…”

ABSTRACT. This paper presents the modified perturb and observe (P&O) maximum power point tracking (MPPT) method for photovoltaic (PV) fed three-port DC-DC converter in PV/battery hybrid system. The proposed MPPT technique reduces the drift problem which occurs in the conventional MPPT methods by including the data of change in current (ΔI) in addition to the data used in the conventional P&O algorithm. The drift phenomenon and its effects are clearly demonstrated in this paper. The ability of the proposed P&O method to address this issue is proved by comparing the conventional P&O algorithm in different modes of operation. The performance assessment includes peak overshoot, settling time, MPP ratio and stability. The experimental validation was implemented using DSPIC30F4011 microcontroller. From the analysis and results, it could be seen that the modified P&O showed better performance in terms of accuracy in tracking the maximum power, less tracking time, high MPP ratio and reduced drift in the changing weather conditions. Keywords: current-voltage characteristics, DC-DC power converters, drift, photovoltaic systems, power demand, pulse width modulation.Impacto da modificação perturbar e observar de controle na MPPT de PV / bateria fed Três -port conversor DC-DC RESUMO. Este artigo apresenta o método de monitoramento de ponto de potência máximo (MPPT) modificado e observado (P&O) para o conversor DC-DC de três portas alimentado por energia fotovoltáica (PV) no sistema híbrido PV/bateria. A técnica MPPT proposta reduz o problema de deslocamento (drift) que ocorre nos métodos MPPT convencionais, incluindo os dados de mudança na corrente (ΔI), além dos dados usados no algoritmo P&O convencional. O fenômeno do deslocamento (drift) e seus efeitos estão claramente demonstrados neste artigo. A capacidade do método de P&O proposto para resolver este problema é comprovado comparando com o algoritmo de P&O convencional em diferentes modos de operação. A avaliação de desempenho inclui o superávit do pico, tempo de estabilização, relação de MPP e estabilidade. A validação experimental foi implementada usando o microcontrolador DSPIC3o30F4011. A partir da análise e dos resultados, verificou-se que o P&O modificado mostrou melhor desempenho em termos de precisão no rastreamento da potência máxima, menor tempo de rastreamento, alta relação de MPP e deslocamento reduzido nas condições climáticas em constante mudança.Palavras-chave: características corrente-tensão, conversores de potência DC-DC, deslocamento, sistemas fotovoltáicos, demanda de energia, modulação de largura de pulso.

“…The common bidirectional DC/DC converter topology includes bidirectional Buck-Boost, Flyback, Push-Pull, etc [18]. As to isolated converter, compound transformer is difficult to be designed, because current is large when low voltage is input and more turns of primary side are needed when high voltage is input.…”

-With the development of science and technology, virtual reality technology as a new technology has been applied to more and more areas. In the traditional shipbuilding industry, the shipbuilding period is usually long and frontline workers tend to make mistakes because of negligence of small details while making ship fitting according to the two -dimensional drawing of the ocean designer. In this study, virtual reality technology is applied to build a three -dimensional solid model in order to realize a vivid expression of the ship model and its assembly process. Compared with the traditional abstract drawing, the three-dimensional solid model allows designers and shipbuilders to be more unified, avoids wasting of resources in the construction process and makes it more convenient for the frontline workers to operate in reality, so as to improve the shipbuilding efficiency and shorten the shipbuilding cycle.
