TL;DR: An energy harnessing network fitted with a Smart Bin in a Waste Management System that will power the Smart Bin and the remaining energy is integrated with electricity grid, acting as a source of energy.
Abstract: Energy crisis in the modern world is one of the major hindrances in Smart Cities. Smart Cities have a lot of energy consuming elements so it is hard to build one using conventional energy sources because of the energy crisis. Reconstructing Smart Cities using unconventional energy sources like solar, piezoelectric etc. is highly complex, and demands innovative solutions. Today many people believe in different ways of ‘going green’ which due to research is supposed to help keep the Earth healthy. One of the major ways that green technology is taking over is through different forms of energy that does not involve fossil fuel. In this paper we have presented an energy harnessing network fitted with a Smart Bin in a Waste Management System that will power the Smart Bin and the remaining energy is integrated with electricity grid, acting as a source of energy. Smart Bins are converted to Green energy source. The main agenda of this paper are to show the paramount importance unconventional energy and inspire people to do further research on Smart Cities.

TL;DR: An IoT based smart predication and monitoring of waste disposal system is proposed which utilizes off-the-shelf components that can be mounted to a bin of any size and measure fill levels and an intelligent neural network algorithm namely Long Short-Term Memory (LSTM) is used to learn and predict the upcoming wastage from waste generation patterns.
Abstract: One of the prominent applications of Internet of Things (IoT) in this digital era is the development of smart cities. In IoT based smart cities, the smart objects (devices) are connected with each other via internet as a backbone. The sensed data by the smart objects are transmitted to the sink for further processing using multi hop communication. The smart cities use the analyzed data to improve their infrastructure, public utilities and they enhance their services by using the IoT technology for the betterment of livelihood of the common people. For IoT based smart cities, waste collection is a prominent issue for municipalities that aim to achieve a clean environment. With a boom in population in urban areas, an increasing amount of waste is generated. A major issue of waste management system is the poor process used in waste collection and segregation. Public bins begin to overflow for a long period before the process of cleaning starts, which is resulting in an accumulation of bacteria causing bad odors and spreading of diseases. In order to overcome this issue, in this paper an IoT based smart predication and monitoring of waste disposal system is proposed which utilizes off-the-shelf components that can be mounted to a bin of any size and measure fill levels. An Arduino microcontroller is employed in the proposed model to interface the infrared (IR), ultraviolet (UV), weight sensors, and a Global Positioning System (GPS) module is used to monitor the status of bins at predetermined intervals. The proposed system transmits the data using the cluster network to the master module which is connected to the backend via Wi-Fi. As data is collected, an intelligent neural network algorithm namely Long Short-Term Memory (LSTM) is used which will intelligently learn and predict the upcoming wastage from waste generation patterns. Moreover, the proposed system uses Firebase Cloud Messaging to notify the appropriate people when the bins were full and needed to be emptied. The Firebase Cloud Messaging (FCM) JavaScript Application Programming Interface (API) is used to send notification messages in web apps in browsers that provide service work support. Hence, the proposed system is useful to the society by providing facilities to the governments for enforcing stricter regulations for waste disposal. Additional features such as automated calibration of bin height, a dynamic web data dashboard as well as collation of data into a distributed real-time firebase database are also provided in the proposed system.

TL;DR: A new design approach achieving very high conversion efficiency in low-voltage high-power isolated boost dc-dc converters is presented, demonstrating that an extensive interleaving of primary and secondary windings is needed to avoid high winding losses.
Abstract: A new design approach achieving very high conversion efficiency in low-voltage high-power isolated boost dc-dc converters is presented. The transformer eddy-current and proximity effects are analyzed, demonstrating that an extensive interleaving of primary and secondary windings is needed to avoid high winding losses. The analysis of transformer leakage inductance reveals that extremely low leakage inductance can be achieved, allowing stored energy to be dissipated. Power MOSFETs fully rated for repetitive avalanches allow primary-side voltage clamp circuits to be eliminated. The oversizing of the primary-switch voltage rating can thus be avoided, significantly reducing switch-conduction losses. Finally, silicon carbide rectifying diodes allow fast diode turn-off, further reducing losses. Detailed test results from a 1.5-kW full-bridge boost dc-dc converter verify the theoretical analysis and demonstrate very high conversion efficiency. The efficiency at minimum input voltage and maximum power is 96.8%. The maximum efficiency of the proposed converter is 98%.

TL;DR: The robust features of the proposed control system ensure a constant output DC voltage for a variety of load fluctuations, thus limiting the power being delivered by the fuel cell during a load transient.
Abstract: In this paper, an analysis and design of a wide input range dc-dc converter is proposed along with a robust power control scheme. The proposed converter and its control are designed to be compatible with a fuel cell power source, which exhibits 2 : 1 voltage variation as well as a slow transient response. The proposed approach consists of two stages: a three-level boost converter stage cascaded with a current-fed two-inductor boost converter topology, which has a higher voltage gain and provides galvanic isolation from the input source. The function of the front-end boost converter stage is to maintain a constant voltage at the input of the cascaded dc-dc converter to ensure optimal performance characteristics and high efficiency. At the output of the first boost converter, a battery or ultracapacitor energy storage is connected to handle slow transient response of the fuel cell (200 W/min). The robust features of the proposed control system ensure a constant output dc voltage for a variety of load fluctuations, thus limiting the power being delivered by the fuel cell during a load transient. Moreover, the proposed configuration simplifies power management and can interact with the fuel cell controller. Simulation and the experimental results confirm the feasibility of the proposed system.

TL;DR: A novel snubberless naturally clamped bidirectional current-fed half-bridge isolated dc/dc converter for fuel cell vehicles (FCVs) and eliminates switch turn-off voltage spike concern with ZCS without any additional circuit, leading to reduced footprints and lower cost.
Abstract: This paper presents a novel snubberless naturally clamped bidirectional current-fed half-bridge isolated dc/dc converter for fuel cell vehicles (FCVs). The proposed converter achieves zero-current switching (ZCS) of the primary-side active semiconductor devices and zero-voltage switching of the secondary-side active semiconductor devices. It is a potential topology for FCVs, front-end dc/dc power conversion for fuel cell inverters, and energy storage. A proposed secondary-modulation clamps the voltage across the primary-side devices (current fed) naturally and eliminates switch turn-off voltage spike concern with ZCS without any additional circuit. This leads to reduced footprints and lower cost. Voltage across the primary-side current-fed devices is independent of duty cycle like conventional current-fed converters but clamped at a reflected output voltage. Therefore, comparatively low-voltage-rating devices with a low on-state resistance are used, introducing low conduction losses and higher efficiency. Steady-state analysis, operation, design, simulation, and experimental results of the proposed converter are reported in this paper.

TL;DR: In this article, a zero-current-switching (ZCS) current-fed half-bridge isolated dc/dc converter has been proposed to solve the switch turn-off voltage spike problem without any additional components or snubber.
Abstract: A novel zero-current-switching (ZCS) current-fed half-bridge isolated dc/dc converter has been proposed in this paper. The proposed converter has potential applications such as front-end dc/dc power conversion for fuel cell and photovoltaic inverters, bidirectional converters for fuel cell vehicles, energy storage, etc. This proposed converter provides a simple solution to the switch turn-off voltage spike problem without any additional components or snubber. It leads to reduced size, lower cost, compactness, and higher conversion efficiency. In addition, the proposed converter has reduced peak current through the components (semiconductor devices and transformer) that reduces their volt-ampere rating and size compared to active-clamped zero-voltage-switching (ZVS) current-fed converters. Voltage across the primary switches is naturally clamped without an additional active clamp or snubber circuit. In addition, voltage across the switch is independent of the duty cycle. ZCS of the primary switches, natural commutation of secondary diodes, and zero-current turn-on of secondary switches are achieved. Therefore, switching transition losses are significantly reduced. Steady-state analysis, operation with the proposed novel ZCS concept, and design of the converter are reported. A 200-W laboratory converter prototype has been built. Experimental results as well as simulation results are presented to validate the analysis and design. A comparison with existing active-clamped ZVS current-fed half-bridge converters has been discussed. The effect of device parasitic is investigated and explained by simulation and experimental results.

TL;DR: The three basic nonisolated DC-DC converter topologies are here compared in a single phase grid tied photovoltaic application, from an efficiency and reliability perspective.
Abstract: The three basic nonisolated DC-DC converter topologies are here compared in a single phase grid tied photovoltaic application, from an efficiency and reliability perspective. A general design procedure which attempts to maximize the switching frequency has been established and followed for all the topologies. A MATLAB® model representing the sources of losses has been developed to evaluate the efficiency, while MIL-HDBK-217F has served as guide to reliability estimation. Graphical and numerical representations of the main results are given, together with a simple figure of merit that synthetically summarize them.
