Title	::	A Bidirectional Series-Resonant Converter For Energy Storage System in DC Microgrids

Page	::	01-09

A bidirectional series-resonant (BSR) converter is proposed for energy storage system in DC microgrid. The bidirectional converters are mainly used in electric vehicles. To determine the voltage gain of the converter, the effective duty cycles of switches are used. Thus the amplitude and direction of the transferred power is not involved, which is an improvement compared with the existing resonant converters. The proposed converter operates as buck and boost converter so that the normalized voltage gain can be regulated from zero to infinity. The direction of power flow and the operation mode can be changed automatically with the simple PWM control. In the entire operation range, ZVS turn-on is achieved for all the active switches. The current flowing through the primary and secondary side of the converter is controlled using current limit control techniques.

Page	::	10-19

In this paper, a modified reduced current ripple DC-DC buck-boost converter, which can be applied for wide range of voltage. The current ripples in the output and input side can be reduced. Reduced current ripple of power electronics supplies has positive effect on efficiency and on the lifespan of sensitive power devices. The DC-DC buck-boost converter are commonly used to deliver higher load voltage from given low voltage source and vice versa. The conventional boost converter has disadvantages are requires a higher duty ratio even for realizing the moderate voltage gain, unable to reach expected levels of voltage gain at extreme duty ratios on account of excessive losses, and the efficiency on full load is low due to higher switching losses............

For low output voltage, high output current systems applications, Synchronous switching power converters give better performance than non synchronous converters. This paper presents an interleaved synchronous buck converter which has low switch voltage stress with high conversion ratio. The input current can be shared among the inductors so that high reliability and efficiency can be obtained and ripples also reduced, the converter performance can be improved. Thus converter features automatic uniform current sharing characteristic of the interleaved phases without adding extra circuitry or complex control methods. Capacitors switching circuits are combined with interleaved four-phase buck converter for getting a high stepdown conversion ratio without adopting an extreme short duty ratio. Synchronous rectifier technology is adopted to increase the converter efficiency. A 30V input voltage, 1.8V output voltage, circuit is simulated to verify the performance. The simulation is done in MATLAB/SIMULINK R 2012a.

Human communication today is mainly via speech and text. To access information in a text, a person needs to have vision. However those who are deprived of vision can gather information using their hearing capability. Book reader is a camera based assistive text reading to help blind person in reading the text present on the text labels, printed notes and products .It involves Text Extraction from image and converting the text to speech converter, a process which makes blind persons to read the text. This is the first step in developing a prototype for blind people for recognizing the products in real world, where the text on product is extracted and converted into speech. This is carried out by using Raspberry pi, where portability is the main aim which is achieved by providing a battery backup and can be implemented as a future technology. The portability allows the user to carry the device anywhere and can use any time.

Renewable sources like solar photovoltaic PV, wind turbines plays prominant role in electricity generation . Photovoltaic PV source is one of the biggest source of world energy requirement.For small applications, solar PV generates energy at low voltage and therefore require a high efficiency DC-DC converter to step up the voltage level. To handle this issue, a coupled inductor based high gain, high efficiency dc-dc converter with intermediate capacitor is introduced. Perturb and Observe algorithm is used to track maximum Power Point (MPPT) in photovoltaic array.

This project presents a multiport converter with pulse width modulation (PWM) and phase shift control for renewable energy systems. The proposed converter works on the principle of an interleaved boost full bridge circuit. The advantages of zero voltage switching (ZVS) and zero current switching (ZCS) is applied in this work. By this method the voltage regulation is improved and powerflow can be regulated. Power flow between the inputs is controlled by duty cycle and voltage can be regulated via phase shift.

Net metering is one of the newest concept that makes a revolution in the current world. This concept has been a tremendous success in many countries like United States, Germany. The idea behind the net metering enables a significant positive response from the people. The consumer, supplied from the utilities for their power needs generates a part of the power from any renewable sources such as sun, wind etc...That part of power produced by the consumer can be used for powering their households. The excess power generated by the consumer can be given to the utilities for which the former are rewarded with reduced electricity bills or it can be credited for subsequent billing cycle. When the power which is generated by the consumer is not sufficient to satisfy their power needs, then the utility power can be consumed...........

Page	::	93-96

Driver drowsiness is one of the most common reason for the road accidents. Sleep disorders causes the fatigue of driver and this results in the increasing number of road accidents. Nowadays about 30% of road accidents is caused due to the alertness of the driver. In order to reduce the accidents related to the driver drowsiness it is necessary to frame a system which accurately detect the drowsiness of the driver. By detecting the drowsiness level and providing a warning to the driver the accidents can be avoided. This paper describes a method which detects the driver fatigue accurately in real time and to provide a warning signal. In this paper Raspberry pi 3 module is used to detect whether the driver is fatigue or not using EAR method. Raspberry pi is used because it is faster to retrieve images from the camera and fast enough to detect a driver's feature in real
time. In this paper a technique to detect driver drowsiness using of Open CV (open source computer vision), raspberry pi and image processing is presented.

Title	::	αβ To Dq (Parke's) Transform Based Control Study On Grid Tied Iverter To Operate As A FACTS Device For Improving Power Transfer Through Transmission Lines
Country	::	India
Authors	::	Madhavadas M || Vibin C Thomas
Page	::	97-103

The power produced by the solar inverter can be linked to grid either in 3 phase or in single phase mode. For low power applications the produced power is linked to grid by single phase power conversion techniques. Most of the power converters work on different conversion techniques at PV-DC side and Inverter- AC side. Here the introduced technique provides both DC and AC sides which are controlled simultaneously (Single stage conversion). The major advantage is that the control provides better time management in isolating and grid tie time requirement. Here a SRF PLL is used, and controlled by Parke's transformation for the AC side, and Fractional Open Circuit Voltage (FOCV) based MPPT control for the DC side is provided. The VSI can be controlled by Hysteresis control mode implemented as an internal loop where the reference current magnitude for this loop is generated from an external Voltage control mode............
