Design of Transformer less Single Phase Inverter

Solar energy is the top of all renewable energy systems because of its pollution free, adaptable, long life, low maintenance cost and favoured options for sustainable development. Thus, this is used as the source of input for this model. The PV cell converts the solar energy into electrical energy. This energy is in DC form. This DC voltage is raised to the desired level with the help of boost converter dc dc converter .The boost converter is driven with the help of MOSFET. The boosted DC voltage is fed to the PWM inverter which converts the dc input into ac output. And finally, the output is given to the load. The proposed inverter system converts DC power into single phase AC power efficiently without using transformers and batteries. In this, the simulation results of a transformer less single phase inverter which uses a photovoltaic array as the input are shown. An inverter with DC link is designed for conversion of DC input into AC supply. The simulation is carried out with the help of MATLAB simulation software. The harmonic distortion is found to be 2.73 in the FFT analysis.

Joining of Dual Phase Coated Steel Sheets DP600

Currently, high strength steels are increasingly used in the production of car bodies. Car manufacturers choose steel with good formability, fatigue resistance, and the ability to absorb impact energy. DP dual phase steels verify the specific criteria mentioned above. Resistance spot welding is one of the most common methods of joining high strength dual phase steels. The paper focuses on the comparison of the properties of joints made by resistance spot welding. Selected properties were investigated by tensile test and metallographic observations. HCT600X Z and HCT600X ZF steel sheets were used for the experiments.

Mechanical Behaviour of AA 6061-Ca2SiO3 Composite

The advantage of composite materials over non alloy virgin metals has been on the front burner in the engineering materials sphere. To this ends, various reinforcement materials are constantly been mixed with metal matrix to form new composite materials. Ca2SiO3 is a ceramic material which finds application in medicine, heat and noise insulation, acid remediation, cement production etc. since it possesses qualities needed for the formation of composites, and is largely not researched on, this study aimed to characterize the mechanical properties of the AA 6061 Ca2SiO3 composite for different composition of percentage mix, and to establish a model that would predict the UTS for known values of percentage mix and load. Result of the study shows that 6 Ca2SiO3 - 94 AA 6061 and 24 Ca2SiO3 - 76 AA 6061 possessed the highest modulus of elasticity and are stiffer while 2 Ca2SiO3 - 98 AA 6061 mix had the lowest modulus of elasticity, and is more ductile than other composition mix. Also, it was observed that addition of Ca2SiO3 to AA 6061 T4 greatly improves its mechanical properties and96.43 of the variations in stress experienced by various percentage composition of the composite mix can be explained by the developed model.

Separate Conductors for AC and DC Supply

AC and DC supplies are ruling in this present electricity world. Involvement of both AC and DC supply can be seen from small circuits to big giant machineries. But is there conductor separation needed for both distinguish supply forms Are we wasting time, money and materials by using same conductors for both dissimilar supplies In my opinion, it is the right time to take decision to separate conductors for both rulers.

Analysis of Power Quality Issues and Implementation of UPQC Topologies to Enhance Power System Stability

Due to the depletion of fossil fuels, coal, and oil, traditional electricity generation has a difficult task for utilities. A cheaper and more efficient method of doing this is required. A different source is required to fulfill the consumers power requirements. The alternate source should be sustainable and capable of meeting the consumers requirements. The integration of renewable energy into the grid is a useful way to fulfill demand. Renewable energy integration confronts three major problems frequency variation, power quality concerns, and power system instability. The following problems were of critical importance. An analytic hierarchy approach based expert system is utilized to identify and categorize power quality incidents. Before, it could sense things like sag, swell, transients, harmonics, interrupts, and flickers. An error free event classification system has been suggested. Simplified procedure allows for improved detection and categorization of power quality incidents. an investigation of power quality incidents and their mitigation using unified power quality conditioners UPQC An Adaptive Neuro Fuzzy Inference System ANFIS is used to minimize various power quality issues. Integrating renewable energy sources efficiently minimizes the environmental impact. The suggested method provides a solution to voltage unbalances and lowers overall harmonic distortion at the point of common coupling PCC . The addition of an ANFIS controlled DVR is used to reduce voltage irregularities caused by integrating renewable energy sources and faults in the transmission line. An artificial fault was added to power quality events with the goal of making use of renewable energy. To minimize the adverse effects of power quality incidents, the ANFIS controlled DVR proposal is in place. ANFIS controlled DVR is contrasted to a traditional technique of surveillance. Distributed static compensator D STATCOM is used to prevent voltage flickers, and total harmonic distortion, caused by nonlinear loads. D STATCOM is suggested to use three control methods Instantaneous power theory, Synchronous vector PI Control, and Harmonic elimination. Under extreme load circumstances, the D efficacy STATCOMs is evaluated. The suggested expert system and the bespoke power devices will be analyzed and discussed using various control techniques.

A Study on Customer Perception of Electric Vehicle and Its Impact on Traditional Supply Chain in India

India traditionally has been belligerent to any changes. But with the need to curb environmental emissions it has been identified that there is a need to switch from ICE vehicles to Electric Vehicles. This switch is eminent and a necessity in order to fight the climatic and environmental changes which is affecting all living life whether in land, water or air. It is a fact that with substantial shift in the automobile industry towards Electric Vehicles disruption in the automobile supply Chain in imminent. It is true that for those suppliers who are heavily leveraged and unable to adapt it could spell a disastrous financial troubles ahead. This study is an attempt to identify how production and supply of electric vehicles will impact the traditional supply chain in India and suggest ways and methods to incorporate the changes. An attempt has also been made in this study to identify the perception of individuals regarding Electric Vehicle. Because it is the people's choice which will lead to boon or bane for this segment of automobiles.
