Chapter I I. Introduction Power electronics converters can be found wherever there is a need to change voltage‚ current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics‚ electrical currents‚ and voltage are used to carry information‚ where as with power electronics‚ they carry power electronics becomes the efficiency An inverter converts DC

Coal power vs. Nuclear power Safety & Efficiency With nuclear power came what was thought to be a more clean alternative to burning coal and other fossil fuels; Nuclear power does not produce nearly as much of the greenhouse gases as coal produces. People and society have given nuclear power a bad name‚ considering the amount of accidents that have happened. Although when you look at statistics it’s not as many as you would believe‚ or expect. When nuclear power is put head to head with coal

LOSSES HOW TO REDUCE THEM AND WHY? KPT-OIPT 013E‚ Published 02.2000. Generally‚ there is a simplified understanding that the socalled load losses in a transformer (load losses‚ PL ) depend on the ohmic resistance of the windings. This is only partly true‚ as the losses arising from magnetic leakage flux in various metal parts of a transformer constitute a significant part of the total losses. This component of total losses is called stray (additional) loss (Ps ). In addition‚ experts distinguish

Console is the section of the imaging system that most Technologists are familiar with. It is the Primary side of the main circuit and it includes the incoming current‚ the exposure switch‚ the autotransformer and the primary winding for the step up transformer. Through the Control Console‚ the tech is able to control the x-ray tube current and the voltage so that the useful x-ray beam that reaches the patient has the right quantity‚ or the intensity of the beam and is expressed in mR/mAs‚ and the right

need for selecting the different voltages used for different parts of the generation‚ transmission and distribution systems drawn for Qu.5. Back in the 1800’s Thomas Edison had a vision to power the whole of New York using DC (direct current) that he developed‚ this idea was brilliant‚ but had one set back. A power station was needed every mile due to D.C. only flowing in one direction. This wasn’t a very practical form of electricity or cost effective‚ another idea or form of electricity was needed
