In many methods, skin and proximity effects are very important. Another important parameter is alternative current (a.c.) resistance, rac. This parameter is frequency dependence. It can be shown that rac increased with the increased of frequency (Du, & Burnett, (2000), (Demoulias, Labridis, Dokopoulos & Gouramanis, 2007), (Desmet, Vanalme, Belmans, & Van Dommelen, 2008). Some research papers used value from published graph such as by The Okonite Company and Anixter Inc. (The Okonite Company, 2001), (Anixter Inc., n.d.). However upon inspection, it was found that the graph is produced on the basis of fundamental frequency of 60 Hz and using imperial unit. Some other sources, although on 50 Hz as fundamental basis, give limited data such as (Moore, 1997), (Coates, n.d). As an alternative, formula from IEC 287-1-1 was used to calculate the rac (IEC, 1994).

It is of great importance in our industries to cut the cost of power controlling with high efficiency and PWM satisfies this criteria. Therefore, it is

I Introduce myself as an undergraduate student specialized in Electronics and Communication Engineering from “Sree Vidyanikethan Engineering College”, Andhra Pradesh which has empowered me to gain an open mindset and intense bits of knowledge. The course curriculum has been a fine blend of theory and practical knowledge during which I developed a keen interest on applying theory in practical.

In this topology, the number of power conversion stages is decreased, there by reducing the number semi conductor switches. So the conduction losses and switching losses are reduced. High frequency transformer is used for isolation because of its reduced size and weight such that it decreases the complexity of the micro inverter. Due to increased switching frequency , the series resonant tank is used to execute the soft switching at the turn on of the power switches to decrease the switching losses. The switching and conduction losses of the inverter are critically analyzed and methods are presented to calculate the size of the resonant components. Thus the outputs are simulated using

Engineering Educational Institutes in India are increasing at a rapid rate to meet the growing demand for engineering graduates across the globe. Enrolment in engineering education has also seen a rapid increase in the last decade. According to AICTE report on growth of students intake in Engineering colleges in the last seven years has increased to three times. Whether all these graduates have acquired necessary knowledge and skills to be employable in the real world is a matter of consideration of all stake holders. The need for addressing the issue of quality in higher education is strongly felt when the students are seen struggling in the global workforce market. According to a latest NASSCOM report the the four major challenges which exist today include employability, infrastructure, favourable policies and competition from other low cost countries. 26% of employable engineers in technology services continues to be a major bottleneck. “There is a strong correlation between a country’s competitiveness and the quality of higher education provided within that country”, say Borahan and Ziarati (2002). Hence measuring and improving the quality of higher education becomes an essential role of higher educational institutions. In the industrial context the customer is the ultimate judge of quality, and the same applies in the academic context, where students are considered as the customers who are the recipient of service( acquiring knowledge /information),

A Thesis Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering

ABSTRACT: -- In this a fuzzy logic control technique has been proposed for power quality improvement by using UPQC The UPQC is controlled to regulate the WF terminal voltage, and to mitigate voltage fluctuations at the point of common coupling (PCC), caused by system load changes and pulsating WF generated power, respectively. In order to reduce the voltage fluctuations that may cause “flicker”, and improve WF terminal voltage regulation, several solutions have been posed. The voltage regulation at WF terminal is conducted using the UPQC series converter, by voltage injection “in phase” with PCC voltage. On the other hand, the shunt converter is used to filter the WF generated power to prevent voltage fluctuations, requiring active and reactive power handling capability. The sharing of active power between converters is managed through the common DC link. A customized internal fuzzy logic control scheme of the UPQC device was developed to regulate the voltage in the WF terminals, and to mitigate voltage fluctuations at grid side. Simulation results show the effectiveness of the proposed compensation strategy for the enhancement of Power Quality.

The scope of this project is to Designed and constructs a prototype that can be used in powering any electrical appliance that required mains voltage from 220v to 240v. The project is limited to a 500VA power inverter, how it work, and its applications. The inverter will incorporate a battery charger an automatic change over that will enable auto back up within 1ms on the event or occurrence of power cut.
