Chapter 844 Our entire point of new goods (first post two chapters, eye problems, and one chapter later)
Just as Tang Shaohui celebrated the success of the velvet technology, and the scenery of the high -chief workers was like the endless rivers, the comrades of the 1218 factory had come to the guest room of the three -point factory.
Walking in here, Director Pan of Factory 1218 was even a little excited.
But it can be considered here, 1274 has come much, I have n’t been here, even if LED technology is provided by Gao Gao workers, it is just sent to the full set of information. Well, there is no need to bother the high -chief workers at all.
Therefore, don't look at the 1218 factory and Gao Zhendong, each in the 12th machinery department, but in addition to Gao Zhendong, the head of Pan Factory, this formal meeting is the first time.
While they looked at the seventeen aircraft ministry with a little curiosity, but in the place where the twelve aircraft department was famous, in fact, the furnishings of the guest room were very simple. They were mainly work. There were no other effective information.
This made Director Pan and Cui of 1218 could not help but think of Liu Yuxi's "Bad Room". This article is really good.
Factory Director Pan and Chief Engineer Cui didn't wait long when they saw Gao Zhendong come in, and they both stood up.
"Hello, Chief Engineer Gao." The two of them greeted Gao Zhendong with their comrades.
Not to mention who asks for whom, even at the administrative level, Gao Zhendong is almost on the same level as him. Even the technical level of Chief Engineer Cui is still far away from Gao Zhendong. As a guest, it is always right to be polite. .
Gao Zhendong sat down while greeted.
"Sit, sit, sit, everyone, sit down. It's hard work for you to make this trip." Gao Zhendong said with a smile.
Everyone said a few words, and Gao Zhendong didn't take much time, and went directly to the topic.
"This time, please be in the ministry that you can come here. Do you know the reason for the reason?" Gao Zhendong is not divided into seventeen and twelve, anyway, it is all in the ministry.
Seventeen: This smells wrong.
Twelve: This is right.
Director Pan nodded: "The ministry has said that they are preparing to develop a high-speed electronic switch."
He handed the 1218 current data prepared in the past few days to Gao Zhendong, and the latter took it over and said as he looked.
"Yes, but it is not all. This electronic switch is just an introduction. In my opinion, if it is smooth, it may be very heavy, not easier than 1274."
Well, the status quo of 1218 is still good, it should be the most suitable job.
Gao Zhendong smiled and brought good news and bad news to Director Pan and others.
Bad news: Heavy duty?
Good news: The task is heavy!
It is necessary to look at things dialectically.
I heard this in the ear of the 1218 factory, happy!
Judging from their understanding, it is no easier than 1274. The actual meaning is as important as 1274. What tasks are not heavy? No existence.
Conversely, if the task is not heavy, it will be boring.
"High chief worker, is it related to the digital integration circuit?" Chief Cui carefully inquired.
Gao Zhendong shakes his hand: "There may be some relationships in the later period, but it is not the main. The most important thing is that you may have to take another road, which is equally important as the digital integrated circuit. , Electric Electronics. "
The two core branches of semiconductor technology, one is the microelectronics technology represented by the work done by 1274, with small power and high integration, mainly for information processing.
The other one is that Gao Zhendong called 1218 Factory here to start another branch, power electronic devices.
Simply put, microelectronics process information, and power electronics process energy. This type of device is the core device when it is necessary to process and convert electrical energy. It is widely used. The four major application directions are related to all aspects of production and life - motor speed regulation, industrial power supply, power transmission and distribution, and lighting. .
If you use Gao Zhendong's most common things in the future, new energy electric vehicles and high -speed rail are not good.
Of course, the application scope of this thing is far from being summarized by electric vehicles and high -speed rail. A more affordable example is the power supply of the computer, not only the switching power supply, but also the motherboard power supply. How much is the garbage guy and DIYer's motherboard every day, and there is at least one electric electronic device in each phase in each phase. In fact, the "phase" in these people's mouths, and the "phase" in the professionalism and change majors is two -coded, which is more suitable for "road". In fact, an important application that the electrical electronic technology does not know is to improve the quality of power supply, improve efficiency, and save energy. It does not produce electricity, but it is just an electric porter, but during the transportation process, let the electricity try to waste or do more.
The semiconductor electronic device was developed in the mid -1950s in the mid -1950s. It began to develop. Like Microelectronics, of course, we also lay out in this regard. In the imitation foreign thyroid device, and some achievements and products are available.
Otherwise, if Gao Zhendong was working on computers, the power supply might not be so easy to make so small.
However, it is necessary to say that the advanced technology is the same as the microelectronics technology when Gao Zhendong began to engage in computer. Basically, do n’t consider it. It is the result of the hard work of our comrades.
And let alone us now, power semiconductors all over the world have some unavoidable problems, otherwise Gao Zhendong would not think about developing new components.
Power semiconductor? Is it a silicon?
As the chief worker of the semiconductor factory, Mr. Cui still knows these things.
"President Gao, are you referring to the thyristor, right? That thing, we have several units in, the rectifier factory in the Northwest, the Songjiang rectifier research institute, and a laboratory of the electronic hospital in Jingcheng are all engaging in this. "President Cui reminded Gao Zhendong.
Gao Zhendong smiled and said: "So many units are doing it? I really don't know, but it doesn't matter..."
How many units are doing now, Gao Zhendong is really unclear, but for him, the problem is not big.
"We engage in a few new devices, which are different from before." Gao Zhendong said his purpose.
There is no mistake, one, one, one, one, one, one, one, one 619, one book, one, one, one, one, one, one, a book!
Although I do n’t know how many units are doing, Gao Zhendong still knows about the development of power electronic devices. He has not been born in this year.
These devices also spent a little time Gao Zhendong, which was picked out of many electric electronic devices. After all, his energy and resources were limited. come out.
The selection criteria are also very simple. They must try to cover as many application scenarios as possible, and the life cycle of the results must be as long as possible. Each type of device must be one that will last for decades, and the technical requirements must not be too high. High, able to comply with the current technical environment.
This job was very taxing for Gao Zhendong. Even though he did well in the power electronics exam, it still took him a long time to recall the characteristics, usage range, life cycle, and technical difficulty of various devices and make comprehensive comparisons. At least a day!
One day!
As an analysis comparison, Gao Zhendong has already spent a big capital.
Putting aside the MCT, SIT, SITH, IGBT, IPM, IEGT, and VDMOS that are too far away and too demanding, there are only the relatively recent ASCR (asymmetrical thyristor), TRIAC (bidirectional thyristor), and RCT (reverse conduction). Thyristor), pure SCR (silicon controlled thyristor), GTO (turn-off thyristor), GTR (power transistor), etc., which made him waste a lot of effort.
However, there is a product that is quite special. Originally, this thing appeared relatively late, but Gao Zhendong really liked it, and it is very easy to use for low power and high frequency. It just so happened that Gao Zhendong, a bad guy, created the birth of this thing. Certain conditions were met, so he was selected in advance.
Fortunately, I finally chose several devices to prepare. As for others, someone should do it, Gao Zhendong will not affect it. At most, it is necessary, help.
Director Pan and Chief Engineer Cui both became excited when they heard Gao Zhendong talking about new components. If Chief Engineer Gao said something new, it must be new. It's almost boring to imitate. It's better to follow Mr. Gao to create new things.
"General Engineer Gao, what components are you going to make?"
However, Gao Zhendong did not rush to tell what he was doing, but brought the topic back to the original goal: "We will talk about that later. After all, it is Zhanwang. For now, let's talk about the starting task, the electronic switch."< br>
Ah yes yes, there is this thing, this is the initial task. Let ’s talk about this first. Although the comrades of 1218 have a little itchy, they still have a curiosity for a while. Explain that today I can get the answer anyway, not in a hurry ...
Don't worry! They felt itchy, but it was useless.
"If you are a high -chief worker, if you are electronic switch, I have also made some preparations. The practical triode can theoretically achieve the effect of the electronic switch. However, some parameters may be adjusted and optimized on the triode."
Mr. Cui's skills are still very solid. Gao Zhendong nodded: "You are right, but this time we will get it right in one step and build an integrated isolation switch."
In principle, Mr. Cui is right, but if you want the electronic switch of this kind of triode to work reliably, the peripheral circuit is a little complicated. It even requires multiple triodes in series and parallel, back-to-back, etc. to complete it. With too many discrete components, the circuit The board area was too much, so Gao Zhendong was ready to take a step forward.
Isolating switch?
"President Gao, do you mean to isolate the control circuit and the charged part on electrical?" President Cui felt that things were gradually interested. A lot, and it is also very practical.
