God-level industrial master

Chapter 189
In Tang Fei's view, Chen Guihong's family background is somewhat mysterious.

Chen Guihong has worked in the Red Star Factory for so many years, and has never used his family's banner or used his family's relationship. This time it is a little different.

The previous general manager of the procurement center, Chen Guihong's predecessor, was furious at the Red Star Factory executives and dismissed him because of the ineffectiveness in importing IGBTs.

Chen Guihong used to be the deputy general manager of the procurement center. He was mainly responsible for the management of domestic suppliers. He entrusted some spare parts to surrounding suppliers for processing, while the head of the procurement center was in charge of imported parts.

Now that something like this has happened, the DJ4 electric locomotive has already entered the final assembly plant for assembly, and when the rice is cooked, it is impossible to purchase imported IGBTs.Chen Guihong's promotion to the general manager of the procurement center is equivalent to being ordered in a crisis.

Many people are looking at Chen Guihong, whether the newly appointed general manager can purchase the urgently needed IBGT. In desperation, Chen Guihong can only use some connections at home.

After thinking about it for a while, Chen Guihong didn't shy away from Tang Fei. He picked up the phone and dialed a number. After the call was connected, Chen Guihong hurriedly said, "Uncle Liu, I have something to ask for your help..."

Tang Fei listened with pricked ears, wanting to know who the person on the other end of the phone was, but what he heard was very limited.

Chen Guihong briefly explained the matter, and asked the other party to help contact the IGBTs of various models and specifications that are urgently needed for the DJ4 electric locomotive imported from abroad, and finally said that this is Chen Guihong's personal request, and his old man must not know .

The other party pondered for a while, but still agreed. Seeing this, Chen Guihong felt relieved.

Tang Fei guessed that the "Uncle Liu" on the other end of the phone should be a leader of a certain ministry in the capital. Chen Guihong was able to directly talk to such a person on the phone, it seems that his family background is really extraordinary.

Tang Fei really wanted to inquire, but Chen Guihong didn't take the initiative to say so, and he didn't want to ask such a personal question rashly, so he could only keep his curiosity in his heart.

But one thing is certain, Chen Guihong's family background is definitely not ordinary.

After making this phone call, Chen Guihong breathed a long sigh of relief, and said with a relaxed face: "Uncle Liu has already agreed, so there is basically no problem with this matter, brother, you can tell me the number, model and number of IGBTs you need. Give me the list of specifications, I'll compile them together, and fax them to Uncle Liu later."

"Okay, I'll send someone over when I get back."

The IGBT matter was basically settled, and Tang Fei felt a little relieved. He chatted with Chen Guihong for a while, and even jokingly said, Brother Chen is promoted, and he wants to treat him to celebrate.

Chen Guihong seemed cautious, saying that now is a special period, IGBTs have not been purchased yet, many people are staring at him, and his seat has not been secured, it is really not the time to celebrate, let's talk about it for a while.

Tang Fei was only joking and didn't take it seriously. He was fully aware of Chen Guihong's situation and did not interfere with his work. He sat down and chatted. After drinking a cup of tea, Tang Fei got up and said goodbye.

Drive back to your company.

Probably because he heard that the boss was back, Zhao Ke came over immediately and asked softly: "Boss, how is the matter? Is there any hope for the IGBT we need?"

Tang Fei nodded and said: "Well, hand it over to Red Star Factory, and Red Star Factory will purchase together. You compile a list of the quantity and model specifications of the IGBTs we need, and after I have a look, send someone to Chen Guihong, the procurement center of Red Star Factory. In the hands of the general manager."

"Ok."

Zhao Ke immediately went to work on this matter, made up the list of the required IGBT quantity and model specifications, and sent it to Tang Fei for review.

Tang Fei took the list, glanced at it roughly, and was a little surprised, "Why are there more types? The latter types are not what our DJ4 traction motor system needs."

Zhao Kedao: "Yes, the latter types are needed for our DJ4 control cabinet. Since we need to purchase them, let's hand them over to Red Star Factory to import them from abroad."

Tang Fei agreed.

This list was also quickly sent to Chen Guihong. After collecting it, Chen Guihong faxed the list to his Uncle Liu.

At present, it seems that the IGBTs needed for the pre-trial production of the DJ4 electric locomotive are temporarily enough. Knowing that Chen Guihong has settled the matter, Chang Jinlin of the Red Star Factory feels relieved.

But Tang Fei takes a long-term perspective. As a reborn person, Tang Fei knows the DJ4 electric locomotive that will be mass-produced in the future, as well as the future Harmony series electric locomotives, including future EMUs, high-speed rail, and subways.

These locomotives all require a large number of "CPUs" of power electronic devices such as IGBTs, especially EMUs, and each EMU requires IBGT of more than 1 yuan.

With such a huge demand, we cannot always rely on imports.

In fact, for a long time in the future, we will rely on imports, importing such things from abroad at a high price, paying a high price, and being stuck by others.

It was not until more than ten years later that the high-power IGBTs required by the rail transit industry were gradually localized, and we gradually got rid of the dependence on imports. Only then did our electric locomotives fully use the IGBTs produced by ourselves.

Huaxia's high-speed rail is world-renowned for its excellent performance, fast and stable driving, and a one-yuan coin can be erected on a speeding high-speed rail locomotive for a long time without falling down.

Such a smooth driving performance is inseparable from the extensive use of IGBTs, the "CPU" in the power electronics field, on locomotives.

Instead of relying on imports and being stuck by others, it is better to develop and manufacture by ourselves.

Tang Fei had this idea a long time ago, and now after this incident, this idea is even stronger. After thinking about it, Tang Fei is ready to do this.

Jiuzhou Industrial Co., Ltd. develops and manufactures IGBTs by itself.

For China's rail transit business, but also for its own future development.Because the future market prospect of IGBT is very broad.

IGBT is the core device of energy conversion and transmission, and the "CPU" of power electronic devices.The strategic significance is extraordinary, and Tang Fei has firm confidence that he must develop and manufacture them.

IGBT is divided into many specifications. For example, according to the voltage, it is divided into below 600V, 600V, 1200V, 1700V, etc., all the way to 6500V, or even higher voltage.

According to the application fields of voltage distribution, those below 600V are mainly used for electronic products, such as digital cameras, those with 1200V are mainly used for household appliances, and those with a higher voltage are mainly used for motor control, electric welding machines, etc. , mainly used in rail transit, smart grid, wind power and other fields.

What Tang Fei intends to do is 3000V and above IGBTs. The target is tentatively mainly for rail transit. After it becomes bigger, it can provide IGBT products with excellent performance for smart grids, wind power and other fields.

Others may be unfamiliar with IGBT, but Tang Fei is familiar with it, and even knows the development and replacement of the entire IGBT.

The first generation of IGBT appeared in 1. It was a planar penetration IGBT. This generation of IGBT had more defects. In 1988, the second generation of IGBT appeared immediately, called an improved planar penetration type.

The third generation, fourth generation, fifth generation, sixth generation and other IGBTs appeared one after another. Now it is 1998. If Tang Fei remembers correctly, the fourth generation IGBT has just come out in the laboratory of a famous electrical group in the United States. .

Tang Fei is well aware of the replacement of IGBTs and the technical differences between different generations of IGBTs. Tang Fei made up his mind that since I want to do it, I will start from the fifth generation.Get started a generation ahead of others.

At present, the second-generation or third-generation IGBTs are mainly used in the international market. For example, the DJ4 electric locomotive needs to use the third-generation IBGT.

The fourth-generation IGBT has just been born in the research laboratory, and has not yet been introduced to the market in large quantities, but Tang Fei knows that since the electrical giant in the United States has successfully developed it, with their strong awareness of patent and intellectual property protection, it is estimated that it has already begun Apply for various patented technologies.

It would be a little inappropriate to develop the fourth-generation IGBT by myself. It may involve their patented technology. It will be more troublesome to say that I am infringing at that time, and get involved in unnecessary lawsuits.

Since we are going to do it, then we will develop the fifth-generation IGBT, leading in the beginning, one step ahead, and step by step.

Tell you to stick our necks, and I will make the fifth-generation IGBT, one generation ahead of you, and let you follow behind to eat ashes.

That's it, let's do the fifth generation IGBT.

The fifth-generation IGBT is also called "electric field cut-off" IGBT. Compared with the fourth-generation, its chip area is smaller, and its performance such as saturation step-down and power loss is better.

The construction of the two professional electrical and electronic workshops is about the same. There is no shortage of workshops. There is a problem with equipment, but since it is decided to do it, the equipment problem can definitely be solved.

The other is professional technical personnel. Since IBGT is to be done, it needs specialized electronics and electrical engineering personnel. Sun Xu is one of them, but Sun Xu alone is not enough.

One hero and three gangs, IBGT's technical team must have a group of people, at least two or three core technical talents, and some technical personnel in the electrical or electronic field will be recruited from outside as supplements.

Tang Fei looked at his "God-level industrial master" system. After successfully developing the DJ4 control cabinet in the simple mode last time, he still had 500 gold coins, enough to summon a core talent in the field of electrical engineering.

Well, call now.

Tang Fei successfully summoned an electrical expert by spending 400 gold coins by specifying the type of summoning, and a new introduction appeared in the system's summoning bar.

Tang Zhonghua, an electronic engineer and an expert in the field of microelectronics, is mainly engaged in the research, design and manufacture of power semiconductor devices...

After reading Tang Zhonghua's basic introduction, Tang Fei was overjoyed. He was lucky to be hit by a single shot. He summoned an expert in the semiconductor devices he needed.

It can be seen that Tang Zhonghua understands electronic engineering and microelectronics, and is better at research in the field of semiconductors.This is almost a tailor-made technical talent for oneself, and it is also an expert type.

With two leaders in IGBT, namely Tang Zhonghua and Sun Xu, and adding a few technical talents, if recruited from outside, then an IGBT technical team can be initially formed.

Everything is ready and ready to go!
