Harnessing wind and solar PV system to build hybrid power system

Electricity is the most important consideration for individual needs. Natural crossover power architecture using photovoltaic and wind is presented in this study, together with a Cuk direct current-direct current (DC-DC) converter, third phase inverter, and an inductors capacitors (LC) filter. Due to its natural disposal and availability in India, wind power and photovoltaics are ideal for the hybrid system. Hybrid power structures, on the other hand, reduce the risk of damage to equipment in sustainable stock storage since they have a higher electrical output. MATLAB Simulink was used to demonstrate this hybrid application. Before connecting the entire DC voltage frame with the main lattice of the power frame, blocks such as the wind model, PV model, Cuk converter, inverter, and LC channel are built individually. Information limitations for participating in varying levels of irradiance and variations in wind speed. The results show that the hybrid system has a considerably more reliable standard in terms of energy efficiency than an independent framework. Furthermore, the hybrid system's Cuk DC-DC converter, three-phase standard-based inverter, and LC channel can minimise power switching power.

Research on Performance Speed Regulation System of Direct Conversion AC-DC Power Conversion Device

With the continuous development of social economy, the application market of electric motors has become more and more broad. Based on the principle of modular design, this paper designs the hardware circuit system of the matrix converter, and completes the parameter calculation of the input LC filter. The modulation algorithm needs to determine the sector and position angle of the input three-phase voltage. The DC speed regulation system powered by the conversion AC-DC power conversion technology is compared with the Buck circuit power supply system. Practice shows that the system has good static and dynamic indicators and load robustness.

Printed Flexible LC Filter Using Additive Micro-Dispensing With Silver Conductive Paste and ECA for Component Attachment

Filters are used in a variety of signal processing applications in commercial and defense electronics. The use of additively printed electronics in high-frequency applications requires an understanding of the process-performance interactions versus frequency of operation. Assembly of filters for integration into existing circuits requires additively printed metallization traces in addition to component attachment methods. Comparison of frequency response of the additively-printed filtering circuits vs conventional filters subtractively-fabricated on rigid substrates is needed to determine the performance parity of additive fabrication methods. In this paper, a micro-dispensing device is used to print conductive traces and electrically conductive adhesive (ECA) pads for the attachment of components. The effect of different print parameters on the width and height of the trace has been studied. Mechanical and electrical properties also play an important role in the study of different sintering conditions. Optimized parameters from the printing process and sintering analysis are used to print and compare commercially available LC filter circuitry using the Bode plot.

New bidirectional step-up DC-DC converter derived from buck- boost DC-DC converter

<span lang="EN-US">This paper proposes a new bidirectional step-up DC-DC converter, namely modified buck-boost DC-DC converter. The proposed DC-DC converter was derived from the conventional buck-boost DC-DC converter. Output voltage expression of the proposed converter was derived by considering the voltage drops across inductors and switching devices. The results have shown that with the same parameter of input LC filter, proposed DC-DC converter has lower conduction losses. Moreover, the proposed DC-DC converter has lower rated voltage of filter capacitor than the conventional boost DC-DC converter which lead to cost efficiency. Finally, a scaled-down prototype of laboratory experiment was used to verify its theoretical analysis.</span>

Solar PV-Wind System Integration with Power Grid System

This paper describes a photovoltaic (PV) and wind hybrid power system that is equipped with a Diode Clamped Multi-Level Inverter and LC filter for the generation of renewable energy. Due to their environmental friendliness and availability, wind and solar energy are ideal for hybrid systems in India. Due to fluctuations in the output voltage, equipment that require a consistent supply will be damaged by hybrid power systems that are completely dependent upon intermittent renewable energy sources. Matlab Simulink is used to create a model of the hybrid system using a Diode Clamped Multi-Level Inverter and an LC filter. Before merging a DC voltage hybrid system with the main grid of the power system, blocks such as the wind model, solar model, Diode Clamped Multi-Level Inverter, and LC filter are developed independently.... The input parameters for the project simulation include different irradiance values and varied wind speeds. Initially, a DC voltage hybrid system with the main grid of power system is constructed separately, taking into account the characteristics of the wind and photovoltaic models developed, as well as the simulation results for hybrid systems with and without Diode Clamped Multi-Level Inverters and LC filters. The input parameters for the project simulation include different irradiance values and varied wind speeds. Present are the wind and photovoltaic model characteristics, as well as simulation results for a hybrid system with and without a Diode Clamped Multi-Level Inverter and LC Filter. The results suggest that hybrid systems are more reliable in terms of generating output voltage than solo systems in this study. As well as this, the hybrid system's Diode Clamped Multi-Level Inverter and LC Filter can reduce output voltage fluctuations.

Multi-Pitch Liquid Crystal Filters with Single Layer Polymer Template

Multi-reflective peak and bandwidth scalable liquid crystal (LC) filters were investigated. By refilling a cholesteric LC (CLC) whose chiral pitch is different to the target template into a blue phase LC (BPLC) template, a multi-reflective peak single layer LC filter can be fabricated. With multiple templating and refilling processes, the number of reflective peaks can be further increased. Moreover, by refilling the CLCs of designed chiral pitch into a CLC template sequentially, a bandwidth scalable single layer CLC filter can be fabricated. The LC filters show great potential applications in optical communication, display, and LC lasing.
