DC to AC Inverter Assignment # 2/ Spring 2013 CE721 Ahmad Ghaffari‚ 1203840 Submit Date: Tuesday 19‚ 2013 Abstract DC-AC inverter is a device that converts a direct current (DC) into an alternating current (AC). When there is no AC main power for applications in caravans‚ remote area and etc.‚ this tool is very suitable to use. It mainly converts a DC source (like a car’s battery) to an AC source (230V) to use for power application like

bu used for wind‚ hydro and photovoltaic systems. Also‚ energy that is stored within the lead-acid battery can be utilizrd as DC current for use in DC appliances such as those found in automotive mobile homes. If Alternating Current (AC) appliances are in place then an inventer must be used to transfer the 12 volts of DC current into the standard 110 volts of AC current for usage by these appliances. Pedal power is the source of getting energy from humans. It can be described as the transfer of

Ques-1: What is a transformer and how does it work? Ans: A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free life. Construction of transformer is very simple‚ two or more coils of insulated

AN OVERVIEW OF THE Shed: This shed was set up in Feb. 1976 by Railway Electrification Organization as a part of Tundla – Delhi electrification scheme and was designed to home 50 electric locomotives at an initial cost of 1.5 crore. The prime objective of setting up this shed was to maintain Electric locomotives required for hauling important mail/express trains on Delhi – Howrah section. The initial holding of the shed was 34‚ all of which were WAM4. At present‚ holding has increased to 138

outstanding contribution‚ as we all know‚ the common incandescent lamp is on AC power‚ because the AC current frequency leads to frequent changes in current big loss‚ light source and transformation is flashing‚‚ LED floodlights can solve the problem very well‚ because he and all the LED lighting‚ adopts low voltage and constant current drive‚ convert the alternating current into direct current‚ and use LED semiconductor light-emitting ‚ not like incandescent tungsten filament consume a large amount

experiment which showed that there was a connection between electricity and magnetism. * When a current was switched on through a wire‚ it made a compass needle turn so that it was at right angles to the wire. * The current had produced a magnetic field strong enough to cause the compass needle to turn. Additional effects due to experiment * It was already known that an electric current in a wire has a heating effect‚ and may cause the wire to glow. This showed that the three phenomena

Inventions like the smart phone‚ light bulb‚ electric current‚ or the remote control would not be possible without Nikola Tesla. Tesla is an inventor from the early 1900s. He is a Serbian-American and one of the most brilliant inventors in U.S. History. He impacted many technological advances far beyond his death. The blueprints he used are still being mapped in today’s works. Tesla revolutionized mankind with groundbreaking inventions that still influences technology to this day. One of Nikola Tesla’s

are non-linear consumers. Non-linear consumers produce harmonic currents which flow through the electric power network. They cancel out in generators and other consumers. The results of those currents are harmonic voltages. Both harmonic voltages and canceling out harmonic currents affect performance of other consumers connected to the electric power network. Because most electrical systems were designed for linear voltage and current waveforms (i.e. nearly sinusoidal)‚ excessive nonlinear loads can

Unit7 Assignment 1 #1 transmission lines are specialized cables and other media designed to carry alternating current and electromagnetic waves of high frequency (radio frequency or higher)‚ high enough that its wave nature must be taken into account. #3 Solid dielectric cable has become the national standard for underground electric transmission lines less than 200 kV. There is less maintenance with the solid cable‚ but impending insulation failures are much more difficult to monitor and detect
