This paper presents coupled inductor interleaved boost converter with LC filter for ripple free current. Based on the conventional coupled inductor interleaved boost converter, two coupled inductor and two LC filter is added to the proposed converter .So the proposed converter achieves reduced input and output current ripple. Hence the ripple ratio of input and output current is reduced. In order to verify that, a proposed converter of 12v input voltage and 24v output voltage operating at 50 khz is constructed. And simulations are verified by using MATLAB Simulink. So the ripple free proposed circuit is used for various photovoltaic applications. Keywords: Coupled inductor, Interleaved boost converter I. INTRODUCTION Nowadays, coupled inductor interleaved boost converter is used in most of the photovoltaic application, electric vehicles, power factor correction. Here input and output current ripple is a major problem in dc-dc converter. The input current ripple of the dc-dc converter is inversely proportional to input inductor current value. So the larger inductor value results in low ripple, on other increasing the inductor value the total weight of the converter gets increased. The proposed converter aims that without increasing the inductor value the ripple should be reduced. So that interleaving of the converter technique is used. By using interleaving technique the ripple is reduced but the weight of the converter is not reduced. So that the new technique called coupled inductor interleaved boost converter technique is used. Here the ripple is reduced than interleaving technique and the weight of the converter is reduced since the core is shared, and inductor was coiled in single core. However, the leakage inductanc... ... middle of paper ... ... ”IEEE Trans. Power Electron., vol. 27, no. 8, pp. 3513–3529, Aug. 2012. 3. Y. Jang and M. M.

Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the first American overland exploration of the American West and Pacific Northwest, departing in May, 1804 from St. Louis on the Mississippi River, making their way westward through the continental divide to the Pacific coast and ending in September 1806. The expedition was commissioned by President Thomas Jefferson and guided byf Meriwether Lewis and William Clark. The exploration covered a total of about about 8000 miles round trip, from St. Louis to the Pacific Ocean. Jefferson trusted in the existence of a Northwest Passage, a water way between the Atlantic and Pacific Oceans. The main goal of the expedition was to locate this Northwest Passage and plan its potential as a waterway for American westward expansion and commerce. Although Lewis and Clark did not find this route, the expedition succeeded in making peaceful contact with Native Americans and uncovering a wealth of knowledge about the peoples, geography, plants, and animals of the western United States. This expedition was an overwhelming amount of work in both preparations and the expedition itself and given the aftermath and achievements was not all for nothing.
In the novel The Catcher In The Rye by J.D. Salinger,Holden the main character tries to take on adult and mature situations but finds himself in reality not getting very far. Holden Caulfield who goes to Pencey has failed four out of five classes and gets the notice that he is being expelled from the school. He leaves the school and goes out and tries to adventure into the real world. Holden takes on many challenges and obstacles throughout the book . Although Holden wants to be independent many people perceive Holden in numerous different ways to his actions and feelings. Faith and Stradlater both perceive Holden as irritating, when in reality he tries to distract himself from being depressed. For example when Holden was in the phone

At the mention jazz music, that people will first think of is likely to be a great figure with a clown image, nicknamed Uncle Satchmo. The man was Lewis Armstrong. He is a husky singer, often with a trumpet in his hand. He played dramatic works of simple structure in Orleans jazz style and with the accompaniment of Dick jazz music. Each of the books on jazz music will mention his name. Lewis Armstrong was to jazz music what Bach is to classical music, Presley is to rock music (Berrett 230). This essay will have an introduction of the king of jazz music—— Lewis Armstrong and his great influence on jazz history.
The Harlem Renaissance was the time period throughout the 1920’s in which entertainment, particularly music, was greatly cherished. It specifically narrowed in on exhibiting black talent and celebrating black culture. The musical movement started in New Orleans, but quickly stretched its way across America, to New York. The flaming passion and emotions that was put into the music during this time is something that is still greatly appreciated today. It is believed that African Americans would not be where they are today, if the renaissance had not occurred. The Harlem Renaissance brought a new sense of identity to African Americans such as Louis Armstrong, Duke Ellington, and Billie Holiday; they were no longer defined as worthless objects in society, they had begun a life beyond that.
normally produce 40% to 100%+ more power (depending on the amount of boost). Boost is any pressure above atmospheric pressure in the intake manifold. When there is more air pressure in the intake manifold that means that there can be more fuel pressure as well. The higher pressure in the combustion chamber means that the
The Harlem Renaissance was an African American progression amidst the 1920s and mid 1930s that was possessed in the Harlem neighborhood of New York City. It began after World War I completed in 1918, African Americans started heading off toward the Northern urban communities wanting to make tracks in an opposite direction from the narrow minded people and its treatment in the South. From the bigot people beating and killing of minorities to hordes lynching various colored people. They got distinctly exhausted on remaining noiseless and started focusing their sentiments into their composed work. The improvement of the "New Negro" amid the Harlem Renaissance symbolized freedom and the last disgrace of slavery(Carroll).The Renaissance offered the way to different capable

...company by subsidies and reduce the cost by incentives on tariff and policy for boost the development of solar energy. Secondly, the low efficiency may improve by the innovation of technology which are the technical and design improvement on photovoltaic systems, storage systems and concentrated solar power systems. The above findings demonstrate the need to mitigate problems with using solar power not only because it is an alternative energy but also because solar power has huge long-term benefits as an endless, sustainable and clean future energy. Therefore, this report recommends that government need more promotion in future to support and boost the research and development of solar energy system which also need the collaboration of the scientist on technical issues. A further recommendation is public encourage in order to widely utilize solar energy in the world.

In recent years the electricity demand in India is increasing rapidly because of fast growing industry. 1.4 billion still has no access to electricity (87% of whom live in the rural areas) and 1 billion that only has access to unreliable electricity networks. We need smart and practical approaches because energy, as a driver of development, plays a central role in both fighting poverty and addressing climate change. The government ofIndia’s make in India campaign will introduce more industry in India then there will be acute demand for more and more reliable power supplies. The energy sources in India is mainly
