Fig 1.1 Block diagram of an Electrical Drive The advancement in electric drive system is very much related to the development in the power semiconductor devices technology. The introduction of the Silicon Controlled Rectifier (SCR) in 1957 has initiated the application of solid state devices in power converters. The development of the electrical

provides a brief description of some of the major stages in the development of personnel/human resource management. With reference to an organisation with which you are familiar‚ note down current practices/initiatives which may fall into each of these categories. (Note: these may include influences from out with the organisation.) Explain why these are important and what effect they have on the management of human resources. |Development |Current practice/

Introduction and Experimental Goal: An electric field surrounds all electrically charged particles. With electric fields‚ one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”‚ the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces‚ changes in motion‚ changes in current flow‚ etc. By using conductive

Q1.)How does training differ from development & education? What is the role of training & development in learning? 1. Training Training tends to be job or skill specific. Besides being specific to a particular job‚ training is also more likely to be a physical endeavor than education. Training entails the practical application of education‚ and thus requires actual movement and motion. For example‚ a medical student will obtain knowledge from classroom education‚ but will ultimately

Advantages and Disadvantages of Electric Vehicles Almost all households in this world uses a gas powered vehicles which causes the greenhouse effect or more known as the global warming. The global warming itself is caused by the emission of the gas powered vehicles. To prevent this‚ technologists have invented a vehicle that uses electricity. Although there are many benefits‚ in a developing countries‚ owning and using an electric car results in having both advantages and also disadvantages.

Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank
