and Implementation of a Single Phase Inverter Circuit 1 INTRODUCTION 1.1 Introduction Inverters are used to produce constant or variable frequency AC output from a DC source. These inverters can be used for AC applicatio n like driving an induction motor. Such type of inverters in present world are used largely in renewable energy systems to convert DC to AC‚ example is a PV system where there is a requirement of such type of inverters which can power AC systems such as an induction

1. INTRODUCTION 1.1) INTRODUCTION OF 3 PHASE INDUCTION MOTOR: The three phase induction motors are used in many industrial applications due to their reliability‚ low cost and high performance. Whereas this popular ac motor performance is affected by following type of faults. 1. ELECTRICALLY RELATED FAULTS (33%): The faults under this classification are single phasing‚ over/under voltage‚ overload over temperature. 2. MECHANICAL RELATED FAULTS (32%): The rotor winding failure‚ stator winding failure

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

The novel “The Circuit” began in El Rancho Blanco‚ Mexico‚ then continues to California. They travel many places in California because they have come to the United States illegally. The characters are Papa‚ Mama‚ Roberto‚ Panchito‚ Trampita‚ Ruben‚ and Rorra. The basic situation is: the family has always wanted to move to California thinking that they will get a better life‚ but instead end up getting worse‚ and being taken by La migra. That is “The Circuit” exposition. The stories central problem

Risk mitigation can be define as the process of implementing any form strategic actions that will reduce the level of threats that may cause financial hardship towards the organization. In addition‚ risk mitigation

Phase Change Lab Written Response Our objective in our phase change lab was to record observations of the increase in temperature (in Celsius) as water changed from solid to liquid to gas over a hot plate. This lab report will discuss quantitative and qualitative data contained in the lab‚ how energy is related to phase change in water and an elucidation of how melting point and boiling point relate to the physical properties of matter. This paper will basically outline the lab done in class
