I. INTRODUCTION 　　Since the industrial revolution started, the acceleration of technology development never stopped. However, with the development of new technologies, environment is suffering the consequences. The rate of Carbon dioxide is increasing rapidly. To mitigate this pollution, the concept of electric vehicle arose. The electric vehicles contribute in reducing the carbon dioxide emissions[1]. Thus, the use of electric vehicles is getting more popular as time goes by. As a result of that

conventional two level voltage converters. The advantages of multilevel inverter are higher power quality, lower switching losses, low electromagnetic interference and higher voltage capability. The voltage source inverter gives an output voltage or a current with levels either 0 or ±V_dc. They are known as two level inverter. To

Relays allow a small current flow circuit to control a high current circuit. 1.2.8 Devices: The devices can be micro-wave oven, bulbs, fans, air cooler, etc which are far away from the user. The micro-controller plays the intelligent part in controlling these devices. 1.3 Working: This project

4. Model predictive control MPC is a general term for computer control algorithms [10] that uses an outright process model to predict future response of the plant. An optimized input is determined by solving an open-loop optimal control problem over a finite time horizon. The number of samples one looks forward is called the prediction horizon Np. While, number of samples that the optimal input is computed for is called the control horizon Nu. The complexity of the problem can be decreased by selecting

A Novel Design of a Double Tail Comparator 1Pedapudi Satish Babu,2N.V.Lalitha 1M.tech student, india, p.satish605@gmail.com. Assistant proferssor,india,lalitha.nv@gmail.com. Abstract: A new CMOS clocked dynamic comparator using two input single output differential amplifier as latch stage suitable for high speed analog to digital converters with the performance of high speed, low power dissipation and low immune to noise. The conventional dynamic comparator requires more power

dc–dc power converter into a three-level dc voltage, and the full-bridge power converter further converts this three-level dc voltage into a seven-level ac voltage. In this way, the proposed solar power generation system generates a sinusoidal output current that is in phase with the utility voltage and is fed into the utility. The salient features of the proposed seven-level inverter are that only six power electronic switches are used, and only one power electronic switch is switched at high frequency

of Solar cells The history of solar cells goes back to the 19th century. Edmond Becquerel was first to notice the effect of light on a certain molecule; in 1839 he found that two different brass plates immersed in a liquid produced a continuous current when illuminated with sunlight. We now believe that he had made a coppercuprous oxide thin-film solar cell. (Fraas, 2016) this property is called the photoelectric effect, and could be harnessed.

1 Introduction This Masters thesis deals with the problem of reactive power compensation in the con-ventional Line commutated converter HVDC transmission. The purpose of the thesis is to develop and implement the reactive power compensation logics for the individual reactive power compensation elements and consequently develop the strategies to optimize the overall reactive power compensation technique in the HVDC LCC trans-mission. Following sections provide an overview of the motivation, objectives
