Comparative Study on Solar Powered Interleaved Boost Converter
摘要： Solar energy is an important source of renewable energy. But, it is unpleasant that, only partial amount of energy can be extracted from the Solar cells by our conventional DC-DC Boost converters. A comparative study on solar powered Interleaving Boost converters (ILBCs) is initiated. A novel Solar powered, Series-Inductor ILBC with less current ripple than the conventional ILBC is proposed. A comparative study on single- stage, two-stage and three-stage ILBCs are done. The comparison of ripple reduction of output voltage is tried with ‘C’, ‘Pi’ and Cascade Filters. The results have been applied to R-Load and motor load. The input of 150V is fed to the ILBC from the solar cell and compared for the ripple. The proposed solar powered series inductor ILBC has reduced ripple than the conventional ILBCs. Comparison table of performance and simulation results of these aforementioned solar powered ILBCs have been exhibited in this paper.

摘要： Induction motors are commonly used in industries due to its reduced cost and minimum maintenance. In this proposed system induction motor is used for the purpose of solar based water pumping application. As the energy consumption is increasing, the energy generated is alone is not able to supply the entire load requirement. Among the available renewable energy sources, solar energy is the leading one. The work proposes a three-phase four-switch inverter for photovoltaic (PV) water pumping or treatment systems. The use of batteries can be avoided, since the converter used in this proposed work is two inductor boost converter. By considering the economic factor and life span of the device, electro-chemical storage elements are avoided. Also an effective intelligent hill climbing algorithmis used to extract maximum power from PV cell. The use of a three- phase induction motor is a better solution to the dc motor for water pumping application.

[IEEE 2018 5th International Conference on Information Technology, Computer, and Electrical Engineering (ICITACEE) - Semarang, Indonesia (2018.9.27-2018.9.28)] 2018 5th International Conference on Information Technology, Computer, and Electrical Engineering (ICITACEE) - Maximum Power Tracking of Solar Panel using Modified Incremental Conductance Method
摘要： Static method to optimize a power delivered by a solar panel is called Maximum Power Point Tracking (MPPT). The method tries to find a maximum power from its PV solar panel characteristics curve using a power converter. MPPT is realized using a buck boost converter and Filter variable step size modified incremental conductance method. Experimental works show that the MPPT system successfully seeks its maximum power and decreases the oscillation during pathway to reach the maximum power. The power generated by the solar panels at 1000 watt/m2 (without MPPT) is 4.17 watt (R = 50 Ω) and 2.37 watts (R = 25 Ω). MPPT system can increase the power to solar panels into 4.48 watt (R = 50 Ω), and 4.32 watt (R = 25 Ω). The power generated by the solar panels at 750 watt/m2 (without MPPT) is 2.53 watt (R = 50 Ω) and 1.48 watts (R = 25 Ω). MPPT system designed also improve the power of solar panels into 3.02 watt (R = 50 Ω) and 3.02 watt (R = 25 Ω). The error steady state in the maximum power condition is 1.188%.

An H5 Transformerless Inverter for Grid Connected PV Systems with Improved Utilization Factor and a Simple Maximum Power Point Algorithm
摘要： Due to their small size, minimum cost, and great efficiency, photovoltaic (PV) grid-connected transformerless inverters have been developed and become famous around the world in distributed PV generators systems. One of the most efficient topologies of the transformerless inverter family is H5 topology. This inverter extracts a discontinuous current from the PV panel, which conflicts with the operation at maximum power point tracking (MPPT) conditions while the utilization factor of the PV degrades. This paper proposes improved H5 topology featuring a boost converter inserted in the middle between the PV panels and the H5 inverter. The design of the boost converter is planned to operate at continuous conduction mode to guarantee MPPT conditions of the PV. A new and simple off line MPPT algorithm is introduced and performance factors like efficiency and utilization factors of the proposed and convention H5 topology are compared. The simulation results indicate that the proposed system provides a preferable utilization factor and a simpler MPPT algorithm.

[IEEE 2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD) - Barcelona (2018.9.17-2018.9.19)] 2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD) - Harvesting artificial light indoors to power perpetually a Wireless Sensor Network node
摘要： Wireless Sensor Networks (WSN) devices are usually battery powered and thereby their lifetime is limited. This issue leads to lose data measurements and thus to a performance loss of the underlying WSN application. It also increases the maintenance cost in Internet of Things (IoT) scenarios with a huge number of WSN devices. Energy harvesting (EH) is one of the key technologies to solve this issue. In this paper, energy harvesting by artificial light is proposed to power WSN devices in indoor scenarios. Contrary to the state-of-the-art related work, this paper experimentally demonstrates that it is possible, under certain conditions, to achieve energy neutral WSN devices by harvesting energy from artificial light. The experimental setup consists of an EH module, which powers a WSN source data acquisition node, and a WSN sink node which receives the data sent by the first. The EH module consists of a photovoltaic (PV) cell, a boost converter and a 3V coin battery.

[Lecture Notes in Electrical Engineering] Microelectronics, Electromagnetics and Telecommunications Volume 521 (Proceedings of the Fourth ICMEET 2018) || Performance Analysis of a PV System Using HGB Converter
摘要： A photovoltaic array based system using a transformer-less high gain interleaved dc–dc boost converter is proposed in this paper. The renewable energy sources such as photovoltaic array and fuel cells provide only a time-varying and low dc voltage which cannot be directly used as the front-end for the loads or dc grid. Hence, there is a need for power electronic interfaces for matching the environmental-friendly sources of energy to the load. The interleaved converter used in the proposed system has the capability of canceling the input current ripple without increasing the component counts in the converter using a preselected duty cycle. Also, the large voltage gain and high ef?ciency of the converter are the added advantages to the proposed system. Analysis, simulation, and experimental investigation of the system proposed were carried out and the results are compared to validate the proposed system effectiveness.

[IEEE 2020 IEEE Texas Power and Energy Conference (TPEC) - College Station, TX, USA (2020.2.6-2020.2.7)] 2020 IEEE Texas Power and Energy Conference (TPEC) - A Simplified DC Capacitor Active Voltage-Balance Algorithm with Common-Mode Voltage Reduction using Active-Zero SVPWM for Three-Level Photovoltaic Grid-Tie Inverter Application
摘要： This paper introduces a digitally controlled single-phase rectifier with power factor correction (PFC) based on a modified three-level boost converter topology. In comparison with the conventional boost-based systems, the new PFC rectifier has about three times smaller inductor and significantly lower switching losses. The improvements are achieved by replacing the output capacitor of the boost converter with a nonsymmetric active capacitive divider, with a 3:1 division ratio, and by utilizing the downstream converter stage for the capacitive divider’s center-tap voltage regulation. The nonsymmetric voltage divider and applied switching sequence effectively provide four-level converter behavior using the same number of components as three-level converters. As a result, a 66% reduction of the inductor compared to the conventional boost-based PFC and a 33% compared to the standard three-level solutions operating at the same effective switching frequencies are also achieved. Experimental results obtained with a 400 W, 200 kHz, universal input voltage (85 Vrms –265 Vrms) PFC prototype demonstrate three times smaller inductor current ripple than that of the conventional boost converter allowing for the same inductor reduction. Efficiency improvements of up to a 6% are also demonstrated.
