I entered the villa and sat down at the reception room.

Vice Premier Hu and all the leaders have not arrived yet, but they first arrived four professors, and a butler of the Hu family introduced one by one, "The top scholar, this is Zhang Jiwei, the professor of mechanical and electrical major you want to find, this is Lin Guorui, a professor of chip research, this is Lin Wenshu, a professor of communications, and this is Lin Yanan, a professor of railway major.

These four professors are all top leaders in China. They were named by our Vice Premier Hu. They all have a lot of graduate students and are all politically qualified talents.

You can trust them with confidence.

Okay, I'll take you five to the study room, and you'll go to the study room to talk.

"When I arrived at the study, the butler introduced it, "It's absolutely safe here. The top scholar, you can say anything secret.

I'll go out first.

"Chen Zhongtian said," Professors, since this is the case, I will not hide it anymore. Let's talk about it directly. First of all, in terms of mechanical and electrical aspects, I found two mobile phone production talents in the United States. One of them is a researcher of precision machine tool production. He has now studied the threshold of five-axis machine tools. We all know that the production of mobile phone accessories requires a large number of precision accessories, so I asked him to set up a machine tool development institute under the mobile phone production factory.

Please note that it is the research institute, not only research, but also manufacturing, so I asked someone to collect old three-axis machine tools around the world, and then we carry out five-axis transformation and upgrading. It is estimated that in a few months, I will be able to transform qualified five-axis machine tools. I need dozens of graduate students to go to Xinbo after the New Year, because our mobile phone manufacturer is located in Xinbo, which can avoid the blockade of Batumi, and we use old machine tools to transform these improved machine tools. These improved machine tools have not been registered in Batumi, so I can secretly transport some of them into China in the name of three-axis.

Professor Zhang Jiwei, you understand what I mean.

""I understand. If you want to make some of their successful five-axis transport to China, you have made great contributions.

You want these ten graduate students to go to the research and development institute first, let them understand the procedures and accessories thoroughly, and then let them return to China with the developed machine tools.

Right?

"Professor Zhang Jiwei asked."

Yes, it's so pleasant to talk to smart people.

Totally correct.

"Chen Zhongtian Dao.

Professor Zhang Jiwei asked again, "How many units do you want to get back?"

""At least 100 units, 50 of which were given to the military and 30 units for my mobile phone assembly factory in Shanghai, so that they also have the ability to process and manufacture accessories.

10 units were given to my dad, and 10 units were given to Shuimu University for use.

"Chen Zhongtian Dao."

I completely understand that you can transport it in the name of three axes without any problems.

I will lead the team to complete this task myself.

"Professor Zhang Jiwei said."

In order to ensure that everything is foolproof, we also need to bring some senior bodyguards and ensure the safety of the personnel.

"Chen Zhongtian instructed."

Understand, it should.

"Professor Zhang Jiwei said."

Let’s talk about chip research. I acquired a chip research institute in the United States, which was founded by three brothers from Fairchild Company. However, they had no money to burn and were looking for investment everywhere. After I found out, I acquired 51% of their shares. I needed more than fifteen graduate students to go to the United States to participate in the research together, and to start learning first, and I can also create the high-power thyristor needed for high-speed rail.

One of these three brothers is a researcher in mobile phone chips, so I set up a mobile phone manufacturer, and the other is a researcher in general-purpose chips such as 8086. I hope that the graduate students who go to study can learn the most advanced technology in the world and bring it back to China.

In addition, I also want to set up a chip manufacturing factory in Xinjiabo, but I have not found a suitable leader now.

"Professor Lin Guorui said, "I understand what you mean. I also plan to take 10 graduate students to the United States in person. I have a friend in the United States, a Taiwanese. I can convince him to go to Xinjiabo to build a chip factory because this is his dream."

Then gradually transfer equipment to mainland China.

But this device may not be the most advanced, and the Batumi is too tightly locked.

""Yes, it is acceptable to be one to two generations behind.

"Chen Zhongtian said."

OK, that's better.

"Professor Lin Guorui said."

OK, let’s talk about mobile phones. I bought Xiaolingtong technology in Japan. This is a game of edge ball, and it actually achieved it based on landlines.

I need someone to help me digest this technique.

"Chen Zhongtian said."

I know that there is a company called Starkang in Yanjing. They are doing this. They named PHS a Chinese name ‘Xiao Lingtong’.

PHS is a wireless local telephone technology that uses 2G communication.

This PHS is a technology from Japan. Have you bought Japanese technology license?

"Professor Lin Wenshu asked."

Yes, I am now grafting this technology with Chinese landlines. This is a staggering ball. Xiaolingtong uses a landline system to bypass 2G licenses.

The Little Lingtong from Starcom has a landline license.

"Chen Zhongtian replied.

Professor Lin Wenshu said, "Well, this solution is not complicated, it just takes time. I will give me three months and I can do it for you."

""Okay, the following is the high-speed rail technology.

There are many high-speed rail technologies, and there are many lines, signals, and communications in the front of the car, but I don’t understand. I only understand one of them is a key technology in the high-speed rail technology mentioned just now, high-power thyristor. As soon as I talk about Professor Lin Guorui, you can understand that thyristor, abbreviated as SCR, is a high-power electrical component, also known as thyristor.

The consumer IGBT field of Simen Kang and Fairy Tong in the United States is now in the world's dominant position, but higher voltages are not enough.

IGBT insulated gate bipolar transistor is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has the advantages of high input impedance of MOSFET and low on-voltage drop of GTR.

The GTR saturation voltage is reduced, the current carrying density is large, but the driving current is large; the MOSFET drive power is small, the switching speed is fast, but the conduction voltage drop is large, and the current carrying density is small.

IGBT combines the advantages of the above two devices, with small driving power and reduced saturation voltage.

It is very suitable for converter systems with DC voltage of 600V or above, such as AC motors, frequency converters, switching power supplies, lighting circuits, traction transmissions and other fields.

The IGBT module is a modular semiconductor product packaged by IGBT (insulated gate bipolar transistor chip) and FWD (freewheeling diode chip) through specific circuit bridges; the packaged IGBT module is directly used on inverters, UPS uninterruptible power supplies and other equipment; what we want to study is the 6500 volt high-voltage IGBT chip with the maximum voltage level and the highest power density.

This technology will be internationally leading.

Each high-speed rail line uses about 3,000 to 5,000 chips, which are arranged in an area of ​​1 square meter and are processed with megawatt-level power. The failure of one chip will cause high-speed rail failure.

Whether it is rail transit, new energy, or industrial frequency conversion, they all rely heavily on this thing."

Professor Lin Guorui said, "I understand that a composite fully controlled voltage-driven power semiconductor device consisting of BJT and MOS.

Damn, Chen Zhongtian, you are so professional, you even know such a professional field.

You are not just an expert in the Internet field, damn, no wonder Stanford University hired you as a professor.

You are simply a genius.
