High Voltage Silicon Diodes

The Diodes $93.99 High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

Silicon Carbide $93.99 Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with a chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been massproduced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light emitting diodes and detectors in early radios were first demonstrated around 1907, and nowadays SiC is widely used in hightemperature/highvoltage semiconductor electronics. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from SiO2 contained in plant material. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Voltage Multiplier $68.51 High Quality Content by WIKIPEDIA articles A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage by means of capacitors and diodes combined into a network. Voltage multipliers can be used to generate bias voltages of a few volts or tens of volts or millions of volts for purposes such as highenergy physics experiments and lightning safety testing. The most common type of voltage multiplier is the halfwave series multiplier, also called the Villard cascade (but actually invented by Heinrich Greinacher). Such a circuit is shown opposite.

Voltage Doubler $54.86 High Quality Content by WIKIPEDIA articles A voltage doubler is an electric circuit with an AC input and a DC output of roughly twice the peak input voltage. They are a variety of voltage multiplier circuit and are often, but not always, a single stage of a general form of such circuits. The term is usually applied to circuits consisting of rectifying diodes and capacitors only, other means of doubling voltages are not included.The Villard circuit consists simply of a capacitor and a diode. While it has the great benefit of simplicity, its output has very poor ripple characteristics. Essentially, the circuit is a diode clamp circuit.

The Blue LightEmitting Diodes $114.71 In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.

Nanocrystalline Silicon $89.22 High Quality Content by WIKIPEDIA articles Nanocrystalline silicon (ncSi), sometimes also known as microcrystalline silicon (cSi), is a form of porous silicon. It is an allotropic form of silicon with paracrystalline structureis similar to amorphous silicon (aSi), in that it has an amorphous phase. Where they differ, however, is that ncSi has small grains of crystalline silicon within the amorphous phase. This is in contrast to polycrystalline silicon (polySi) which consists solely of crystalline silicon grains, separated by grain boundaries.

High voltage power electronics market and technology trends

The power electronics market is booming at all voltage ranges!
More importantly, power devices for application markets >1.7kV like wind power converters, electricity transportation and distribution (T&D), rail traction and ship & vessel propulsion correspond to high added-value businesses.

It is sure that their total 2010 expected market size of $405 million (including power devices and power modules) is small compared to lower voltage markets, but they remain very dynamic and offer the potential of high margins.

These market developments are primarily driven by energy saving considerations and green technology developments. They are actively supported – e.g. electricity T&D – by several governments and leading companies are working to improve their technology.

As such, IGBTs, thyristors (GTOs and IGCTs) and diodes will get access to more and more technological improvements like transition to 8'' wafer platforms and use of silicon carbide (SiC) materials among others.

However, the long time period of order contracts, the low volume production they imply and the issues to increase voltage to use SiC-based components induce quite light competition between the well-established players of those markets.

Market metrics

Total market for high power devices and modules (including IGBTs, thyristors and diodes) was $390 million in 2009 and is expected to ramp up to more than $570 million by 2015.

Rail traction will contribute more than 65% of this value because of the high level of production it represents and the number of inverter units per locomotive.

Electricity T&D will benefit from the strongest CAGR between 2010 and 2015: 11.1%. Indeed, we expect plenty of work to be realized for HDVC transportation, and ABB to provide an important contribution to HVDC light architecture by making IGBTs.

Wind turbine converters have not suffered so much from the 2009 crisis, and their growth is expected to be the second strongest, with 2010 – 2015 CAGR of more than 9%.

Finally, ship and vessel markets have been impacted unevenly in 2009. Military vessels have kept on growing – relatively to the long time period of ship manufacturing – whereas passenger yachts acquired for private use have drastically decreased. As a consequence, we estimate the global IGBT module market for ships and vessels to resume in 2013 and reach $26 million by 2015.

Report Highlights

Power electronics represent a daily challenge in several systems today (photovoltaic inverters, hybrid electric and electric vehicles, cameras, white goods,…) from a market point of view, but also from a technology development aspect.

Plenty of companies are pushing R&D efforts hard in order to provide the most cost-effective, efficient and reliable materials, devices and systems. And some more "hidden" applications, like the over-1.7kV segment described in this report benefit from those efforts.
The 4 following segments have been investigated in this report:
- Wind turbine converters,
- Electricity T&D,
- Rail traction,
