characteristics. First, an IGBT chip with high blocking voltage, reasonably low on state voltage, and sufficiently wide safe operating area had to be developed. In lower voltage devices, a buffer layer structure (a.k.a. PT-Punch Through) similar to a PIN diode (figure 1a) was found to be optimally effective for this purpose. The buffer layer in these devices was formed as part of the epitaxial silicon wafer. Adapting this structure to a high voltage device requires a very thick epitaxial layer which presents

Panels,” Cooler Planet explains the inner workings of solar panels by stating that: “Solar panels are made up of multiple individual solar cells, which act as large semi-conductors and utilize large-area p-n junction diodes. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable

The conventional DC–DC converters have the disadvantages of operating at high duty-cycle, high switch voltage stress and high diode peak current. Non-isolated high step up converter overcomes this drawback. This converter reduces voltage stress on switch by using clamped-capacitor circuit which is helpful to reduce the conduction losses by using low power rated components and efficiency will increase. Single switch is used in the non-isolated high step up converter, thus reduce the entire cost of

Devices The purpose of this paper is to give a greater understanding of the semiconductor world, for Physics 100 students who have a little knowledge of electronics. I will cover conductors, insulators, semiconductors, and the operation of a diode and a transistor. The reason that it is important to understand these devices is the vast effect that they have had on our modern world. Our lives are filled by electronics, especially in this computerized age that we live in, and I have found that

INTRODUCTION For years, infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now, infrared LED has evolved into a system of significantly greater importance and use. Throughout the world, it is now being used to transmit voice, television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result, millions of dollars are being spent

Microcontroller (ATMEGA328): The ATMEL, ATMEGA328 is a is a low-power CMOS 8-bit microcontroller based on the AVR enhanced architecture. By executing powerful instructions in a single clock cycle, the ATmega328 achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed. The ATMEL AVR core combines a rich instruction set with 32 general purpose working registers. All the32 registers are directly connected to the Arithmetic

Generators-Primary Cooling Water Circuit functioning : In order to distinguish the treated water from the secondary coolant (raw water, condensator etc.) it is named as primary water because it is used for cooling stator winding, phase connectors and bushings . The secondary cooling absorbs the heat from the primary cooler when water is circulated in a closed circuit by the primary water cooler. The pump is supplied with in primary water cooler. Water is supplied to the flow paths of the generator

Purpose In the present era where energy demands growing rapidly the solar module is one of the solutions and a good one. “More energy from the sunlight strikes the Earth in one hour (4.3 × 1020 J) than all the energy consumed on the planet in a year (4.1 × 1020 J)” therefore solar energy has a bright future ahead. The first solar cell was invented in 1953 and had efficacy rate of 4 present while toady’s solar cell is 40 present efficient. SolarCity is using the one of the efficient solar panels which

Traditional Infrared Touchscreens Touchscreen interactive devices have become increasingly important in both consumer and commercial applications. They’re a large component of many everyday devices from your mobile to your chromebook. They’re “electronic visual displays that can detect the presence and location of a touch within the display area (Bhalla, 2010).” There is considered four different groups of touchscreen technologies each with its distinct advantages and disadvantages with some of
