“…The flyback converter has been widely used in a large number of power conversions due to its relatively simple structure, good performance, and galvanic isolation [26][27][28]. A bidirectional buck/boost converter is a mature topology in power electronics systems due to its simplicity and high efficiency [29]; however, the conventional buck/boost converter cannot Compared to traditional converters, with the addition of the realization of conventional bi-directional function, the multifunctional converter can also be applied for both the isolated and non-isolated operation modes.…”

“…As conventional bidirectional isolated or non-isolated converter control methods and strategies have been widely presented in the literature, details on the related control analyses and design are provided in [26][27][28][29][30][31][32][33][34][35][36][37][38]. Given that the proposed new converter has many different transition control strategies across different states and modes, the switching control is mainly used during the transition process between the switching devices depending on the application requirements.…”

Abstract:In this paper, a multifunctional isolated and non-isolated dual-mode low-power converter was designed for renewable energy conversion applications such as photovoltaic power generation to achieve different operating modes under bi-directional electrical conversion. The proposed topology consists of a bidirectional non-isolated DC/DC circuit and an isolated converter with a high-frequency transformer, which merge the advantages of both the conventional isolated converter and non-isolated converter with the combination of the two converter technologies. Compared with traditional converters, the multifunctional converter can not only realize conventional bi-directional functions, but can also be applied for many different operation modes and meet the high output/input ratio demands with the two converter circuits operating together. A novel control algorithm was proposed to achieve the various functions of the proposed converter. An experimental platform based on the proposed circuit was established. Both the simulation and experimental results indicated that the proposed converter could provide isolated and non-isolated modes in different applications, which could meet different practical engineering requirements.

“…Street lighting enables people to illuminate streets, roads, and pedestrian crossings. It helps reduce the number of accidents on the roads and provides light for pedestrians and drivers at night [1]. In the traditional version of street lighting, sensors work only during darkness, but energy is expended on the light when lighting is not needed.…”

Traditional street lighting systems receive data about daylight levels and adjust lighting. However, in such conditions, energy consumption increases since the sensors of such systems receive data on only one indicator which is daylight. Therefore, a suitable automated intelligent lighting system model is needed. Intelligent lighting systems can adjust the brightness of the light not only based on natural data, but also based on the movement of vehicles and people. This paper describes the development, implementation, and testing of a smart lighting system model to increase energy efficiency and high reliability. This system is controlled by a micro-controller programmed to control the lighting and receive data from sensors for processing with good efficiency. Distributed sensors record environmental conditions such as daylight and traffic. Photo-resistors change resistance in daylight to light up the streets at night. The HC-SR501 infrared motion sensor detects objects emitting infrared radiation (heat) in the controlled motion zone and sends a signal to the micro-controller. The intelligent lighting system uses LED's, which consume less energy and achieve high efficiency. Calculations show that the efficiency of using these lamps is almost 70%, compared to what is used in conventional street lighting systems.

“…TREET lighting is experiencing a remarkable evolution due to the combination of LED lighting, renewable energy sources and energy storage systems yielding a new concept called Lighting Smart Grids (LSG) [1], [2], [3]. They ought to be flexible, reliable and also efficient in order to accomplish the decisive requirement of energy efficiency [4]. The recent emergence of high-power LEDs brings new opportunities to modernize street lighting systems in our hometowns [5], [6].…”

A methodology for LED placement in luminaires without lenses for optimal illumination of complex target areas

Street lighting still faces some challenges, e.g., reducing power consumption, lowering light pollution, and making adaptive luminaires more effective among many other concerns. It is evident that the arrival of light emitting diodes (LEDs) in lighting systems has altered the state of the art and design strategies in lighting. In a traditional approach a single lamp, i.e., a single light point, is used. Then, by means of lenses, the specification of the radiation pattern is met. However, LED lamps allow for higher flexibility. It is possible to configure many small light sources, positioned and oriented at will. In this paper, a novel software tool able to provide the most suitable solution starting from a certain target lighting specification is proposed. This tool specifies the smallest number of LED required, their geometric orientation and power levels in order to comply with all the specifications. It is especially useful when trying to light up an irregular, twisted area, although this methodology can be adapted to any geometry. Furthermore, to validate the proposed methodology, two lamps were tested in the streets of Oviedo, Spain using a staggered arrangement.
