Blocking diode The blocking diode is a helpful tool for limiting the direction energy can flow through a wire to just one direction. It uses a semiconductor P/N junction achieve this behavior. The diagram shows a simple setup with two panels charging a battery (for simplicity no controller is shown) with a blocking diode in series with the two panels, which are also wired in series. When the sun shines, as long as the

Losses for Three-Phase Circuit Using Power Diode Shrinivas Reddy Dept. of EEE,PDACEG, GULBARGA Abstract In this paper a zero voltage switched active network (Fig. 1) used in combination with three-phase ac to dc diode rectifiers is presented. It is shown that

Nick Holonyak and the Invention of Light Emitting Diode (LED) Introduction Nick Holonyak was born in the United States of America in Zeigler, Illinois on the third of November in 1928. He was the son of the immigrants from the country, which is currently called Ukraine. Holonyak studied electrical engineering at the University of Illinois at Urbana-Champaign, where he attained his Master’s along with his Ph.D. degrees and graduated in 1954 (Holonyak, 1962). He worked at the Bell Telephone Laboratories

Light emitting diode or LED technology is a new sensation in commercial and residential lighting applications. Every dark area that needs to be brightened and every object that needs indication is now becoming lively with LEDs. The reason is simple, world is striving to save energy, and LEDs are stars in field of energy efficient technology. The dominating advantages of LED over the conventional lighting like; incandescent bulb and CFL, makes them the best choice for every new installation and upgrade

Light emitting diodes, also known as LEDs have really changed the way people think about lighting. An ordinary incandescent light bulb uses up 90% of energy it consumes as heat. Also, they last about 900 hours. The LED lasts about 25,000 hours, which is equivalent to 22 years. This is a major difference. Origins of the Technology: In 1962, Nick Holonyak Jr. invented the first light emitting diode, also known as the LED light bulb. He was a general Electric researcher. Some of the first work done

In recent years, serious innovative work has been conducted on organic light- emitting diodes (OLEDs) for the acknowledgement of high-efficiency colour showcases, backdrop illumination and illumination applications. Notwithstanding, a low light outcoupling productivity still firmly restricts the general proficiency on the grounds that exclusive a little part of light can leave the multilayer structure because of the extensive contrast in the refractive list between air (n = 1.0), glass (n =1.5) and

Abstract: Energy is one of the issues that is causing the most controversy as fossil fuels are the greatest pollutants and the greatest contributors to the greenhouse effect .The increasing importance of environmental concern, fuel savings and unavailability of power has led to the renewal of interest in renewable energies. It therefore stands to reason that developing countries whose energy consumption rate is increasing at a very fast rate should be investigating new energy systems based on renewable

Primary Cooling Water Circuit In The Generators : The treated water used for cooling of the stator winding, phase connectors and bushings is designated as primary water in order to distinguish it from the secondary coolant (raw water, condensator etc.). The primary water is circulated in a closed circuit and dissipates the absorbed heat to the secondary cooling in the primary water cooler. The pump is supplied with in primary water cooler. The pump is supplied with in the primary water tank and delivers
