The first batch of high-power IGBTs has begun to be manufactured, these days, Tang Fei will basically go to the production site every day to have a look, and today he arrived at the production site early in the morning.

If all goes well, the first finished IGBT should be successfully manufactured.

Sure enough, now Zhao Ke came over, holding the first manufactured IGBT, and put the things on Tang Fei's desk.

Seeing this IGBT, Tang Fei came to the nature, took it and looked happily, and after looking at it, he said with satisfaction: "Well, it's really good, at least the appearance quality is first-class." ”

Zhao Kedao: "Boss, it is far more than the appearance of first-class quality, its comprehensive performance is even more first-class." ”

This is the fifth generation of IGBT, looking at the world, only here, it is enough to lead the mainstream IGBT on the market two generations, the generation difference between the two generations, the performance is not good.

Coupled with the addition of Tang Fei's quality +1 BUFF, the IGBT produced is of first-class quality, and Zhao Ke's mood at the moment is even higher than Tang Fei's.

The first high-power IGBT has been successfully manufactured, which also makes Jiuzhou Industrial Co., Ltd. the first domestic enterprise to master the complete industrial chain of IGBT chip design, chip manufacturing, module packaging and system application, filling the gap in the relevant technical fields in China.

The news spread quickly.

In the afternoon, many employees of Jiuzhou Industrial Co., Ltd. knew that their company had completed a feat and successfully produced the first high-power IGBT.

"It's been successfully manufactured, our company is amazing!"

"I heard that it is still a high-power IGBT, and the DJ4 electric locomotive of the Red Star Factory needs such a thing!"

"We can produce this thing, and I feel like when I go out, my waist is much straighter. ”

“……”

From the words of the employees, they can be heard full of pride and joy. Yes, the first high-power IGBT was produced and manufactured, filling the domestic gap in one fell swoop, what a proud thing!

In addition to being happy, Tang Fei instructed Zhao Ke and others to produce several other high-power IGBTs, which are needed in the rail transit industry.

After a while, we will produce other types of IGBT, and strive to use one or two years to achieve serialization and familyization of IGBT, from 600V to 6500V full coverage.

His first batch of high-power IGBTs was manufactured, and Tang Fei personally went to the Red Star Factory and brought samples of this IGBT.

First go to Xie Zhenhua's office.

When he knocked on the door and entered, Xie Zhenhua was not there, and the door of the office was hidden, Tang Fei knew that Chief Engineer Xie should have gone to the assembly workshop, and he should have personally paid attention to the assembly of the DJ4 electric locomotive.

Xie Zhenhua is really in the assembly workshop.

He first looked at the assembly progress of the first DJ4 electric locomotive, after so many months of assembly, this car gradually entered the final stage, several major systems have been installed on the car, such as motor traction system, control system, variable voltage and flow system and so on.

Xie Zhenhua personally boarded the car, looked at it with satisfaction, and knew that there would be no problem in getting off the car in about two or three months.

Next, he went to see the second DJ4 electric locomotive on the assembly bench next to it, which entered the train a little later and was still a long time before it finally got off.

Today, the assembly of the traction motor system is underway, which is the motor traction system developed and manufactured by Jiuzhou Industrial Co., Ltd.

"Everyone, be careful, slow down. ”

Seeing that the assembly workers were hoisting a traction motor onto the locomotive and preparing to assemble the motor, Xie Zhenhua stood next to him and said loudly.

A supervisor in charge of technical guidance said: "Chief Engineer Xie, don't worry, we won't make any mistakes." ”

Xie Zhenhua looked at everyone's traction motor system assembly and was about to go back to his office, when his mobile phone rang, it was Tang Fei calling.

"Chief Engineer Xie, I came to your office and brought you good things, are you interested in coming over and taking a look?" ”

Xie Zhenhua was suddenly interested, and immediately said loudly: "Okay, I'm in the assembly workshop, I'll come over immediately." ”

Tang Fei waited for about a few minutes, Xie Zhenhua came back, and as soon as he entered the door, he said loudly: "Tang Fei, you brought me something good." ”

Tang Fei smiled, took out the things he had brought, put them on Xie Zhenhua's office and said, "Take a look, what is this!"

Xie Zhenhua began to open the package with great interest, this is something packaged in a carton, open the carton, there is foam and bubble wrap inside, and the contents are protected and packaged very well.

Finally, Xie Zhenhua took out the things inside and put them on his desk, at this moment, Xie Zhenhua's heart beat invisibly faster, because he had already seen what it was.

IGBTs He has seen that the Red Star Factory has purchased a batch of imported IGBTs, some of which have been installed on the two DJ4 electric locomotives that are currently undergoing final assembly.

The IGBT in front of me is a little different from Xie Zhenhua's common IGBT, it seems to be more high-end and more advanced.

This is the fifth generation of IGBT!

Xie Zhenhua said excitedly: "This is the IGBT you manufactured, or the high-power IGBT, which is exactly what we need on our DJ4 electric locomotive." ”

"Yes!" Tang Fei said: "This is the first batch of high-power IGBTs we produced, and there is an instruction manual for this IGBT in the box." ”

Xie Zhenhua found this manual, looked at it quickly, and after reading it, he gave a thumbs up, "Tang Fei, it is worthy of the fifth-generation high-power IGBT, and the performance is really so good." ”

Tang Feidao: "In addition to this high-power IGBT, we will also produce several other types of high-power IGBT, and we will produce all the IGBTs needed for DJ4 electric locomotives in the near future." ”

"Okay, great. Xie Zhenhua almost applauded happily.

After chatting with Tang Fei and learning about some IGBT manufacturing, he took the IGBT and said excitedly: "Let's go, let's go to Mr. Chang to report the good news, he should be in the office." ”

Xie Zhenhua took this IBGT and strode in front, and the two entered Chang Jinlin's office one after the other.

Chang Jinlin saw what Xie Zhenhua was holding in his hand at a glance, stood up suddenly, and said in an uncertain tone: "Old Xie, what is this, is it IGBT?"

Xie Zhenhua nodded and said: "Yes, it is a high-power IGBT produced by Tang Fei, and it is the fifth generation IGBT, and there is a manual here." ”

Chang Jinlin first read the manual, after reading, and looked at this high-power IGBT with great interest, when he learned that Jiuzhou Industrial Co., Ltd. will produce several other high-power IGBT in the near future, Chang Jinlin was excited.

In this way, all the IGBTs needed for the DJ4 electric locomotive have been settled, and suddenly, Chang Jinlin felt relaxed.

After asking Tang Fei about IGBT, Chang Jinlin said loudly: "I want to book a plane ticket, I want to go to the capital, and report the good news to the leaders above, we have successfully produced the first high-power IGBT in China." ”

Xie Zhenhua agreed: "This is indeed worth a trip to the capital, such a big happy event, but also to make the leaders above happy." ”

Tang Fei said that he had no opinion, and his first batch of high-power IGBT production was destined to drop a bombshell in the domestic rail transit industry, so that the upper echelons knew that it was okay.

A few days later, the first batch of high-power IGBTs manufactured by Jiuzhou Industrial Co., Ltd. was successfully delivered to the Hongxing factory.

Chen Guihong, the leader of the procurement center, personally received this batch of IGBTs, personally signed the delivery receipt, and personally saw the physical objects of this batch of IGBTs.

Yang Jun felt like he was in a dream, and after quietly pinching himself, Yang Jun still couldn't believe it.

"Mr. Chen, this is really an IGBT, and it is the IGBT that we need on our DJ4 electric locomotive, which is so exciting!"

After speaking, he picked up an IGBT in his hand and couldn't put it down.

The first batch of high-power IGBTs was sent to the Red Star Factory, all of which were qualified and there were no defective products. This incident also caused quite a stir in the entire Red Star Factory.

Some middle and high-level leaders of the Red Star Factory are talking about this matter, and the words are full of praise, everyone knows that the imported IGBT stuck neck is no longer a problem and will no longer be stuck in the neck.

In one of the offices, where Siemens' staff at the Red Star plant worked, Cross listened to a report from his subordinate, Joseph.

After listening, Cross said, "Is this thing true?"

Joseph said with great certainty: "This matter is absolutely true, the entire Red Star Factory has spread, Jiuzhou Industrial Co., Ltd. has indeed succeeded in manufacturing the first batch of IGBT, and the things have been sent to the Red Star Factory, and now it has entered the warehouse of the Red Star Factory." ”

That's really the case!

Cross pondered, he had heard some of them, and now after listening to Joseph's report, he was even more sure that it was true.

At present, Siemens and Hongxing Plant are in a cooperative relationship, and Ximen Company guides Hongxing Factory to produce and manufacture DJ4 electric locomotives.

It's just that for the sake of technical secrecy, many of the core components are originally shipped from overseas, and the Red Star Plant just loads them on electric locomotives.

High-power IGBT is also the core and important part of IGBT, and Siemens has its own stable procurement channels and can easily buy these things from the international market.

In their opinion, the Red Star Factory should be able to buy these things relatively easily, so the original agreement stipulated that these IGBTs would be purchased by the Red Star Factory itself, and Siemens would only provide a list of the models and quantities of these IGBTs.

Where did he think that the Red Star Factory had many difficulties in the procurement of IGBT, Cross saw all this in his eyes, and thought in his heart, it is estimated that it will not be long before Chang Jinlin will come to him and beg him to help the Red Star Factory purchase these things.

Chang Jinlin didn't come over, but there was amazing news that Jiuzhou Industrial Co., Ltd. successfully manufactured the first batch of high-power IGBTs, and the things have now entered the warehouse of the Red Star Factory.

Cross walked up and down the center of his office with his hands behind his back and a slight frown.

Today's two shifts, the second shift is complete!
