Regarding the working characteristics of IGBT insulated gate bipolar transistors, if Mr. Huang can really answer, Fu Xin really wants to keep Mr. Huang shouting at his peers!

Not to mention anything else, MOS gate power switching devices were introduced to the world as the pioneer of the IGBT concept, and it was only in the past two years, that is, in 1979, that the pioneer of the IGBT concept MOS gate power switching devices came out.

In addition, in Fu Xin's last life, he did not see that China really has a completely independent IGBT "China Core", because the completely independent IGBT "China Core" is until September 12, 2013, China's independent research and development of high-voltage and high-power 3300V/50AIGBT insulated gate bipolar transistor chip chip and the high-power 1200A/3300VIGBT module packaged by this chip passed the expert appraisal before it came out, at this time, Fu Xin has crossed.

It's a pity that Mr. Huang is not Fu Xin's colleague, he has never even heard of the English abbreviation IGBT, and he can't answer Fu Xin's question at all, "Uh......" Mr. Huang's face turned red.

However, the most important thing for pure researchers like Mr. Huang is their thirst for new knowledge, so after a while, Mr. Huang asked Fu Xin shamelessly: "Comrade Fu, I apologize for my previous prejudice against you, can you tell me about this IG BT?" ”

"It's IGBT, the full name in English is insulated_gate_bipolar_transistor, and the Chinese name is insulated gate bipolar transistor." Fu Xin corrected.

Fu Xin then continued: "It is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar triode) and MOS (insulated gate field effect transistor) and MOSFET...... The high input impedance and low on-voltage drop of the GTR are both advantages.

The GTR saturation voltage decreases, the current-carrying density is large, but the driving current is larger. MOSFETs have very little drive power and fast switching speed, but they have a large on-voltage drop and a small current-carrying density.

IGBT combines the advantages of the above two devices, with low driving power and reduced saturation voltage. It is very suitable for use in converter systems with DC voltage of 600V and above, such as AC motors, inverters, switching power supplies, lighting circuits, traction drives and other fields.

The year before last, that is, in 1979, MOS gate power switching devices were introduced to the world as the pioneer of the IGBT concept. It was it that started the research on IGBT insulated gate bipolar transistors, and I don't know much about the rest, I also saw it in a foreign scientific magazine. Fu Xin didn't dare to say too much, if he said too much, it would be shocking.

In fact, when Fu Xin said "both MOSFETs", he realized that he had made a serious mistake, that is, he exposed his advanced knowledge, but when it came to this point, he could only bite the head and completely explain the concept of IGBT insulated gate bipolar transistor, and then he could only expect that these people in front of him did not understand, and then forgot about it.

"It is very suitable for use in converter systems with DC voltage of 600V and above, such as AC motors, inverters, switching power supplies, lighting circuits, traction drives, etc...... It's a good thing, it's a pity that our country is lagging behind, and it is estimated that there are few people who know this IGBT insulated gate bipolar transistor. The world in the future belongs to you young people, we are old, and the future of the country depends on your support! Old Man Huang said with sadness.

Fu Xin nodded heavily, and then said: "Old man, don't worry, we will definitely inherit the wishes of our ancestors and build our country into a prosperous, strong, and free!" You're still young and you're sure to see the day! Fu Xin doesn't have a grudge against this stubborn old man, this is an old man who has been running for the country all his life, and he deserves respect.

"I hope so, I don't know how many years I have to live, old man! Come on! The old man didn't say much.

……

Fu Xin returned to Huaxing Electronics Factory with satisfaction, and with Mr. Huang, the "head snake", he basically figured out the situation of Xunyang Electronics Factory. Not only that, Fu Xin also learned an important news from Mr. Huang, that is, Mr. Huang knew that Xunyang Electronics Factory was going to be taken over by Xunyang. City. The government gave it up for sale because he was an important figure in Xunyang Electronics Factory and participated in the city. The Great Discussion of the Government.

However, the Xunyang Electronics Factory was not sold to all of the Huaxing Electronics Factory, but to carry out the shareholding system reform and sell about 40 percent of the shares of the Xunyang Electronics Factory to form a joint venture.

Fu Xin told that he had ideas about Xunyang Electronics Factory, and he assured Mr. Huang that he would not have major surgery on the personnel management of Xunyang Electronics Factory, but would only carry out major reforms in technology, and would also improve the treatment of workers.

In this regard, Mr. Huang was very happy, from the mouth of the army and others, he knew that Fu Xin was indeed a good factory director, therefore, Mr. Huang threw a blockbuster news to Fu Xin, that is, there is a foreign company interested in Xunyang Electronics Factory, and a company in Xiangjiang is also interested in Xunyang Electronics Factory, so the two joined in and made Xunyang. City. The government is chaotic.

Xunyang. City. There is also no unity within the government, and the mayor's faction tends to hand over part of the shares to the foreign company to form a joint venture; And the municipal party committee. Secretary Li Zhenbang and his faction believe that the foreign company is not well-intentioned and is only interested in the skilled workers of the Xunyang Electronics Factory, because they have already established a factory in Shenzhen, and Xiangjiang is a part of China, and it is obviously more reassuring to hand over the Xunyang Electronics Factory to the people of Xiangjiang. Therefore, it is resolutely disagreed to hand over the Xunyang Electronics Factory to foreigners.

It was the struggle between the two factions that caused the problem of Xunyang Electronics Factory to drag on until now, giving Fu Xin the opportunity to enter.

Hearing this blockbuster news, Fu Xin was quite shocked, a foreign company, a Xiangjiang company, said that there was no pressure, it was false. However, the pressure is under pressure, Fu Xin is still quite confident, these outside enterprises, willing to pay the price is not high, just give some money, temporarily accept the workers, the government agreed to the joint venture, because Xunyang Electronics Factory is now a big burden for the government.

Fu Xin thought: "Mother, you have the right, but you are reluctant to spend money, but labor and management are willing to spend money!" If you can't fight you at the political level, then labor and management will crush you to death with money! ”

Fu Xin really thinks so, Li Zhenbang estimates that there is not much to help him on the surface, and the only person who can directly help him may be Mr. Huang, so at the political level, he can't fight those two at all. But there is money to pay the new, the military's order is almost completed now, and before the year, the military can pay off all the money, and he will pay the new one, and there is no shortage of money at all.

The profits earned from the military are enough to completely buy the Xunyang Electronics Factory. Fu Xin doesn't believe that the two will pay a big price to jointly venture Xunyang Electronics Factory, there are many business opportunities in China now, and they don't need to fight with themselves on this! Therefore, Fu Xin is full of confidence in winning Xunyang Electronics Factory.

……

"Fatty, when is your father at home?" Fu Xin asked Chen Guanyu.

Chen Guanyu was a little puzzled, this Fu Xin, specially came here to find his old man, could it be that something happened to Huaxing Electronics Factory, it happened that he had recently heard some rumors about Huaxing Electronics Factory, so he frowned and said to Fu Xin: "Xinzi, if Huaxing Electronics Factory really has a big problem and can't do it, you just give up, sell the factory, you should be able to make a profit, don't force it!"

Then you and Brother Liu will come to the Carrefour store together, and we will not turn you two away. Our Carrefour store is developing very well now, and we are about to open a third branch, and I am a little busy with Orange and Condor Man. ”

Fu Xin smiled bitterly, it seems that the matter of Huaxing Electronics Factory has spread a little widely, but it is almost about to be solved, and Yenching University, with the efforts of Chen Daisun, has agreed to transfer the relevant technical information of the transistor. On my side, Anshui has a strong ability to provide water and has found a new source of goods in Shanghai, although the price is a little expensive, but it is acceptable; One of the thyristors, the bidirectional thyristor, is also to be successfully studied, and the army has guaranteed that he can make the bidirectional thyristor by the end of the year. The only difference now is how to take down Xunyang Electronics Factory!

Fu Xin said: "Fatty, where do you want to go, I'm looking for your father, although it is related to Huaxing Electronics Factory, but it's not what you think at all!" ”

"What's that? Don't you just want him to help you? Chen Guanyu couldn't figure out what Fu Xin was thinking, except for seeking his father's help to see if he could solve the crisis of Huaxing Electronics Factory, what else was there? Probably not.

Fu Xin pursed his lips and said, "I did come to ask your father for help, but it's not what you think." I ask your father to help me see if I can set up a Huaxing Industrial Development Company! ”

Chen Guanyu listened, frowned and thought about it, and then said bitterly: "Huaxing Industrial Development Company has become a company again, Xinzi, what do you want to do?" Since you came back from the army, I have found that you have really changed a lot, although many of your ideas are right, but you can't always be so imaginative, do whatever you want, if you make a mistake, it's over! ”

Fu Xin has nothing to explain about this, his behavior, in the eyes of others, is indeed whimsical enough, but what should be done must be done, and he will reform too!

For Chen Guanyu, there is no need to hide this matter, Fu Xin believes him, Fu Xin said: "The reason why I want to set up this Huaxing Industrial Development Company is that I want to merge and acquire an electronics factory, Xunyang Electronics Factory, that electronics factory is of great use to me!" However, because that electronics company needs to let the government control a part of the shares like Carrefour, I can't merge him to Huaxing Electronics Factory. ”

"What? I didn't understand too much, you can tell me more carefully. Chen Guanyu is still a little confused.

Fu Xin was not impatient, and patiently explained: "Let me tell you this, when I set up this Huaxing Industrial Development Company, in the future, Huaxing Electronics Factory and Xunyang Electronics Factory will become subsidiaries of this company, and the part of the shares I occupy in the Carrefour store will also be placed under the name of Huaxing Industrial Development Company." The subsidiary can allow others to control a part of the shares, but Huaxing Industrial Development Company, the parent company, I control all of them, so as to avoid unnecessary equity disputes, understand! ”

Chen Guanyu suddenly realized and said, "You are a group!" Say it early! So many roundabouts. ”

Fu Xin was not too surprised that Chen Guanyu knew the word group, and said that part of his family was a red capitalist, Fu Xin replied: "There is no definition of the concept of group in China, I'm not afraid that you don't know!" ”

"Hehe, Xinzi, don't you look at what kind of person I am Chen Guanyu!" Chen Guanyu said proudly.

Fu Xin said: "Okay, I know you are amazing, you can tell me now, when is your old man at home!" ”

"He'll be home tonight." Speaking of this, Chen Guanyu's words changed, "But Xinzi, although I and the old man of my family both know the concept of the group, but I am optimistic that you can do it, there is no definition of this above, you let people want to do it for you, and there is no way to start!" ”

In this regard, Fu Xin knows that the earliest national normative document in China on the establishment of enterprise groups and the definition of enterprise groups is the "State. Body. Reform Commission, State. Pass through. Several Opinions of the CPC Committee on the Establishment and Development of Enterprise Groups".

But isn't it just to avoid this trouble that he has made so many new rounds!

Fu Xin said: "Let's go find your father first!" If you don't do it, how do you know if you can succeed? In addition, I will also inform my other master, Mr. Chen Daisun, who is a well-known economist in China, who should be able to help me in this matter. Now I have even done such an outrageous thing as a wholly-owned acquisition of an electronic component factory, and it is not difficult to do an outrageous one! ”

In fact, Fu Xin pinned more hopes on Liu Xiaojun, and told Liu Xiaojun, the intermediate contact, that he was going to establish Huaxing Industrial Development Company, and asked Liu Xiaojun to tell the above that since the above regarded him as an experiment, this request should be able to be agreed! Fu Xin thought so.

As for discussing with Chen Guanyu's father, it was because Chen Guanyu's father was the chief political officer of Yicheng, and the last time he wholly acquired the electronic component factory, he didn't tell Chen Hong, which caught Chen Hong, the chief official, off guard, and attracted some dissatisfaction from Chen Hong.

Chen Guanyu knew that Chen Daisun was a big bull, but he didn't know that Fu Xin was still Chen Daisun's disciple, so he exclaimed: "Mr. Chen Daisun! Xinzi, you have the ability! Don't talk about your Taoist master, a mysterious character, and now you worship a big cow as a teacher, you are really full of adventures, comparable to Duan Yu's turbid son! ”

Fu Xin knew that Chen Guanyu was joking, so he pushed him, and then said with white eyes: "Go aside!" I don't want to compare with Duan Yu, although my love for Xiaoying, and Xiaoying's temperament and appearance are not weaker than Wang Yuyan, but before I met Xiaoying, I was not as romantic as Duan Yu!
