Rebirth of the Military Industrial Overlord

What is IGBT? Is it worth Tan Zhenhua to have this thing at all costs with Siemens?

It is still a bit complicated to explain what this thing is from a professional point of view, but we can see from its scope of application why it has such an important position in Young Master Tan Er's mind.

IGBT, English full name InsulatedGateBipolarTransistor, Chinese full name "Insulated Gate Bipolar Transistor", you can see by the name, this is a semiconductor device.

I won’t explain its working principle here. It’s too confusing for non-professionals to understand. I just talk about its purpose-it is commonly used in DC equipment converter systems such as motors, inverters, switching power supplies, lighting circuits, and traction. Transmission and other fields are the core components of energy conversion and transmission, commonly known as the "CPU" of power electronic devices.

Still don't understand?

To put it simply, all high-power electrical appliances, from the refrigerator and air conditioner of your home, to electric cars, electric rail locomotives, smart grids, aerospace vehicles, power supply systems for various ships, etc., must rely on this special "CPU" comes to normal operation. Without it, there would be no modern airplanes, high-speed rails, subways, Tesla, BYD, 055, large flatbeds, J-20...

Because all these equipments are large power consumers, there must be such a "heart" or even n such "hearts" to coordinate the power distribution and transmission of each unit.

Some classmates are about to say, Qianzhiyu, nonsense, how can IGBT be so important, it won't work without it? How about before this thing? Does the earth turn?

This is really worth talking about.

In 1987, IGBT was really a new thing. At least before 1979, there was no such thing as IGBT in the world. Well, so, before that, you should not expect human beings to make high-power electrical products. How good is the performance-because engineers at the time used a lot of electronic components to combine together to achieve similar functions, but now, only a chip is needed.

Do you understand this way?

Just like the giant computer that could only be installed in one building during World War II, its computing power is not as good as the current roadside store selling calculators for 5 dollars.

As a radar expert in the past life, Tan Zhenhua certainly knows the importance of IGBTs, and this is also the component that worries him the most—because for the large power-consuming radars, the function of IGBTs cannot be replaced at all and cannot be avoided, but In terms of product performance and reliability, even in 2017 when Tan Zhenhua is reborn, China’s products will still lag far behind the international leading companies. Can eat in the low-end market.

Looking at the market share at that time, you can know: At that time, Huaxia owned half of the global IGBT demand market, but this market was divided by the three companies of the United States Fairchild, Hans Infineon, and Toshiba from Japan.

Seeing the names of these three leading companies in the IGBT field, some students have to ask again: "Young Master Tan Er had a good time in Wa, and his relationship with Toshiba is even more affectionate than Jin Jian. Come to West Hans to find Siemens to solve this problem? And there is no Siemens among the three leading companies?"

Um, this, because it involves the field of electronics, Tan Er is quite proficient in the history of its development. If you want to do this now, you can only find Siemens.

Because Tan Zhenhua has long been inquiring about it, the priority of this thing in Toshiba's internal research and development is far lower than the technical upgrade of DRAM. Therefore, although Toshiba has continued to invest in this technology and has achieved certain results, it is far from practical. It's still early. What's more, they are currently concentrating their full energy on launching a DRAM war against the South Korea Semiconductor Group headed by Samsung. At this time, they are fighting inextricably, and they will not be able to take action for a while.

As for Fairchild, Tan Zhenhua believes that he has acquired a lot of technology from the United States and has aroused thoughtful ideas, unless there is no way, he does not want to put eggs in a basket, especially the basket is still in the nest of the Americans. Put in.

So it is Infineon who can make ideas and is worth making ideas.

However, Infineon Semiconductor, a company that no one knows about playing electronics in the 21st century, does not yet exist.

Well, because it is only the semiconductor department of Siemens.

Understand this time?

And up to now, the only company in the world that has really mastered the full set of IGBT technology is Siemens. The Americans are still in the laboratory stage, although in fact, the American GE (General Electric) company was the first in the world in 1985. They developed industrial samples, but for unknown reasons, they gave up on further development on this basis and sold them to Fairchild (Tan Zhenhua guessed that there is a high probability that GE believes that this will hinder GE’s More expensive and complex systems were sold to the military for a lot of money, and on the other hand, they misestimated the market demand and believed that it was not worth wasting time and other resources.)

And Fairchild? On the one hand, the recent situation is not good, and the brain drain is serious. (For example, the Big Three that founded Intel is the representative of them). Its technical capabilities are no longer what it used to be; Assimilation always takes a certain amount of process. Therefore, even if Tan Zhenhua finds them, they will be willing to sell them, and a big question mark needs to be put on the things that really get them.

In comparison, Siemens, which has made a lot of achievements in the electrical industry, originally has a wide range of needs for IGBTs. Technological progress will directly bring this company more advanced products and better cost performance, so they will be keen on this aspect. Carry out product and technology upgrades.

Judging from the statements of Ernst von Siemens and Dr. Karl Henz Kaske, it is clear that Siemens has a clear understanding of the wide range of uses and important roles of IGBTs in the future, and they will never exchange them easily. Even Tan Zhenhua quoted a very high price tag.

Both parties insisted on this. It seems that the possibility of reaching an agreement today is almost zero, but the businessman, business is not righteous, so when Mr. Siemens bid farewell, Tan Zhenhua still politely sent him out.

But to be honest, his deep heart is still very regrettable, because he knows that now is the best time to get the IGBT technology, because this thing has not yet demonstrated its great value, and it has not attracted many people. Attention, even organizations like "Batumi" have not even noticed its existence, so in terms of international relations, there are no political obstacles to getting this technology now, but if it passes another paragraph Time is hard to say.

It seems that we have to find a way to force Siemens to make the old stubborn resolve.

When Tan Zhenhua was thinking about it, he suddenly smelled a faint scent on the tip of his nose. The smell of this scent seemed familiar, and he couldn't help but smile and stood up to open the door.

"Susan, I didn't expect you to come too, but welcome," he said.
