Let's take a look at the history of tablet PCs. The first tablet used in business is the GRiDPad manufactured by GRiD Systems, which was launched in September 1989. Its operating system is based on MS-DOS. Unexpectedly, the first tablet also used the DOS operating system.
The real name of the Tablet PC was in the fall of 2002, when Microsoft promoted Windows XP Tablet PC Edition and became popular. Its appearance made the tablet go to the public, and the tablet began to gradually Appeared in the eyes of computer consumers.
But the real detonation is that on January 27, 2010, Apple released its tablet PC product - iPad. According to the information released by Jobs at the 2011 new product launch conference, the iPad tablet sales in 2010 have reached nearly 15 million units. . Subsequently, many international brands such as Dell, Hewlett-Packard, Lenovo, Motorola, and Blackberry joined the battlefield. For a time, the development of tablet PCs and various products emerged in an endless stream, so it was seen that this was the golden age of tablet PCs.
Compared with the earliest positioning in the business market, tablet PCs are now completely synonymous with "game consoles". In the face of blind consumption, the iPad’s practical use of the iPad is almost just one. The game console for entertainment is the same as the handheld game consoles such as PSP and NDSL.
So who is the enemy of the tablet?
The rapid development of smart TVs and large-screen smartphones has become the biggest enemy of tablet PCs.
As of mid-2014, smart TVs grew by as much as 636, which seriously impacted the home entertainment market. The most direct impact was the decline in sales of large-sized tablets. However, the housing leaks coincided with the night rain, and the invasion of large-screen smart phones made the tablet market, which had been struggling, suffer again. Take the Apple iPad as an example. The sales volume has been declining for three consecutive months, even as high as 16%.

The question is, do we still need a computer that is not too big?
In fact, BlackBerry CEO Thorsten Heins had thrown out "a five-year tablet death theory" as early as 2013. He said that tablets will not exist for five years. Maybe you need a big screen device at work, but it should never be a tablet. The tablet itself is not a good business model.
So in the life scene, especially at home, smart TV greatly meets the needs of entertainment and games, especially in the game experience, multi-person participation, the big screen experience will completely subvert the tablet.
Is the traditional tablet really dead like this?
The author believes that the traditional tablet PC represented by the iPad has achieved the ultimate in price and technical indicators, but lacks innovation in the use of the product. In other words, the traditional tablet PC does not have the product function ease of use. Fully played to the extreme.
Taking the business market as an example, the tablet PC in the entertainment field has entered a bottleneck period, but it has just emerged in the mobile office field. In fact, the current notebook is still the main tool for business people to move the office, but the problems of heavy, short standby time, and inconvenient Internet access are always irritating. And the tablet computer properly solves these problems, more and more business people will choose to carry a business tablet with them when they are on a business trip to solve the problem of mobile office. The laptop is the same as the desktop, and will only be turned back when you return to the office.
In business negotiations, the demand for computers is not only high definition, but more needs are ease of use, individuality and fashion, and even breakthroughs in product features, such as tablet with projection function, convenient Anytime, anywhere projection, easy to conduct business negotiations.
For example, the most recent feature of Lenovo's YOGA 2 tablet is the addition of a pico projector. It is built into the thicker edge of the body and can output images with brightness of 40-50 lumens, maximum size of 50 inches, and resolution of 854×480. The demand for business scenes for various occasions is undoubtedly a huge bright spot.
However, the most amazing thing is that the YOGA 2 tablet actually designed a “hole†in the back, fully taking care of the special scenes such as kitchen scenes and outdoor scenes. This micro-innovation is behind the re-understanding of user needs. It is also a rethinking of the functionality of the tablet.
In the face of the impact of smart TVs and big-screen smartphones, where is the future of tablets? According to the author's understanding, in the future, in the rediscovery of the user market, the redefinition of user needs, grasping the functional and sceneual personality needs, the tablet will have a future.
Scope of supply
Rating: Up to 200MVA
Voltage:Valve side voltage up to 1000VDC, Grid side voltage up to 220KV
Double star and double bridge
Applications:
The rectifier transformers are mainly used in the electrolysis processes for production of different kind of metals, such as aluminum electrolyzing, magnesium electrolyzing, copper electrolyzing, zinc electrolyzing and other more applications. The largest installed rectifier transformers are always for aluminum electrolysis with some transformer/rectifier combined units in parallel operation to get the required DC current.
Design:
The rectification method is normally known as double star or double bridge. Double star systems use an interphase transformer (IPT) and are usually applied as 6 or 12pulse units where high currents are required with very low nominal voltages. Double bridge system is applied as 6, 12, 24, 48 or 60pulse systems, as required to suit the harmonic mitigation and process stability requirements.
Duty
Electrolysis is normally a continuous process, but with a constant high loading and current harmonics.
