Chapter 239 GTOGTO, the word in Secretary Lu's mouth certainly does not mean GreatTeacherOnizuka, but the meaning of turning off thyristor, GateTurn-OffThyristor.

Please search ()!

The fastest updated novel is the former by the great teacher Hideyoshi Onizuka, and the latter is an extremely important power electronic device used in power engineering.

Needless to say, the GTO can be thought of as an electric switch that can be opened and closed instantaneously.

It's just that it's not the human finger that controls it, but the power signal.

By loading high and low voltages at the gate level of the thyristor, the shutdown or opening of the thyristor can be controlled.

This characteristic of GTO enables it to be applied in the field of chopper speed regulation variable frequency speed regulation inverter power supply, etc., it can be said that without it, there will be no "big power grid" in modern society

。

It is very simple that in order to be able to work normally, the power grid of each power station transmits large currents to the substation, and if there is no GTO equipment that realizes the power conversion and control circuit, the power grid will be lit into a torch for people/br > every minuteThis shows the importance of GTO and the entire family of power electronics in which it is located in human society, and their wide range of uses.

However, although the GTO is more advanced than ordinary thyristors, it still has unsatisfactory aspects.

For example, the switching speed and frequency are low, the power required to drive the switch is high, and the circuit to realize the switch is too complex.

This leads to zhìGTO is obviously a consumer product, but it has become a luxury product in terms of cost.

The construction of power grid is restricted by power electronic devices, and the conductor cannot be intelligent and large-scale, which has become a difficulty in the application of power energy.

The leader served by Secretary Lu received a report from the Chinese Academy of Sciences system before that.

In the report, he reported on his thoughts and progress in approaching Motorola to build the first modern wafer fab in China.

In addition, it is to prepare an epoch-making product for its future wafer fab, that is, IGCT.

Before Hu Wenhai's rebirth, there was only one letter difference between the IGBT produced at BYD's Ningbo wafer factory.

The meaning is not much the same.

IGCT, integrated gate commutation thyristor.

IGBT, Insulated Gate Bipolar Transistor.

Both are power switch electronics, plus GTO technology, the three can be said to be in the same vein.

In a simple comparison, GTO is a low-frequency, low-speed, but ultra-high-current power switch driven by high voltage, and IGCT is a high-frequency, high-speed, high-current power switch driven by medium voltage.

IGBT is a high-frequency, high-speed, high-current power switch driven by low voltage.

The difference is huge, but in practice it is very different.

The smallest GTO device is the size of a box.

In the era when there were no IGBTs or IGCTs, this undoubtedly limited the application range of power electronic devices.

IGCT, on the other hand, is reduced to a box size, which undoubtedly greatly reduces the cost of power electronics.

And what about IGBTs?

Don't look for it, pick up your phone, the IGBT is hiding there, the small one can be crammed into the small space of the phone.

Without IGBTs, there would be no modern electronics, and this statement is absolutely true.

IGBT gives humans the means to intelligently control electricity, as small as the power control of mobile phones.

From the power control module of electric vehicles to the automatic control core of China's high-speed rail.

Modern society operates on electricity, and IGBT is the reins of the wild horse of electricity.

BYD took the lead in making a breakthrough in the IGBT at the electric vehicle level, and in the following years, Zhuzhou CSR made a breakthrough in the IGBT at the high-speed rail bullet train level.

These two breakthroughs are two of the countless times that China has broken the monopoly blockade of foreign advanced technology.

Hu Wenhai is a little proud of this, because he has made some contributions to China's IGBT independence.

Now it is born again.

Of course, he will not forget about the IGBT as a big killer.

It's just that the technical requirements of IGBT are too high, and he hasn't even built a wafer factory, so how can he run without learning how to walk?

So he remembered IGCT, this "Zhou Yu" who was born at an inopportune time

。

IGCT is truly born at the wrong time, and it is both born and bright.

When IGCT was proposed in 1997, IGBT also made a breakthrough.

In front of IGBTs with all-round advantages.

IGCT, which is only half a step away, has persevered for 11 years, but IGBT has become a general trend by virtue of the advantages of low-voltage drive and continuous reduction of chip cost.

Eventually, the IGCT was replaced by the IGBT and became an unremarkable piece of history.

If IGCT technology can be developed in the 80s, Hu Wenhai has a foundation for many big toys to be realized.

To put it simply, the car racing competition, which is completely monopolized by Europe and the United States, will be divided into two parts in the future.

Why should the oil-burning and the electricity-burning ones compete separately?

The electric racing car can accelerate to 100 km/h in 2 seconds.

Gasoline powered racing you try?

At the end of the day, the petrol racing race simply flipped the table and didn't play with the electric racing!

Hu Wenhai really wants to get the IGBT drum out quickly, and when the time comes, he will drive to the rally arena and slap Mercedes-Benz, BMW, and Toyota in the face one by one.

"Mr. Hu, Mr. Hu?"

Secretary Lu called softly twice, which brought Hu Wenhai, who had a ** smile on his face, back to his senses.

"Ahem. ”

Hu Wenhai pretended to cough twice, changed his serious face, and said in a deep voice: "Yes, I have a technology in my hand that can replace and upgrade most of the GTO devices, and improve the performance of the thyristor switch by a considerable margin. But first of all, I want to know, can I get state support for this technology?"

"Mr. Hu, what do you want the country's support for?"

Secretary Lu asked cautiously.

Hu Wenhai spread his hands and said with a smile: "The simplest point, if I take out the technology and have an ultimatum to review the experts, can the construction market of the State Grid be opened to me?"

"It's not that I cherish myself, I think Secretary Lu should also know what level of development of China's power electronic devices is. After I take out the technology, it is impossible for foreign companies to be indifferent, and they will definitely follow up with the development. Whether it can win in the market competition depends on the development progress of subsequent supporting technologies. This requires enterprises to reinvest the profits of the previous products. However, if Xinke can't get the domestic market, it will not be able to have enough profits to compete with other international companies. ”

"Rather than making foreign manufacturers cheaper in the end, it's better not to take out this technology. ”

Hu Wenhai's words are reasonable, and Secretary Lu is really hard to refute for a while.

What's more, he has followed the leaders from the power department to his current position, and it can be said that he is very familiar with China's power construction.

There is no need for performance improvements.

As long as the cost of GTO devices can be significantly reduced, this is enough to form a fatal attraction for the Ministry of Electric Power Industry.

But the problem is not nothing, the power system and other monopoly sectors in China, such as railways, telecommunications, petrochemicals, tobacco and other industries, have a problem, closed.

The mountains and circles in the system are everywhere, and the needles outside the system cannot be inserted into the water and splashed.

Hu Wenhai's technology can really replace the GTO, so the original production ...... Wait a minute.

Hu Wenhai vaguely remembered that in the 80s, there was no GTO in China.

The power adjustment is made of thyristor, that is, a simple thyristor, and there is no switching.

What should we do if this new technology of cross-generational improvement leads to equipment upgrades and technical changes, resulting in internal instability?

Essentially, a closed system like electricity instinctively hates any change.

To put it simply, it's one word, lazy!

Without realistic motivation and pressure, there will be no active demand for progress.

The only way to break this closure is through pressure from above.

This is also the reason why Hu Wenhai found the leader behind Secretary Lu.

This leader from the power system will undoubtedly play a decisive role in whether he can take this piece of cake.

Secretary Lu also spread his hands helplessly, but said with a wry smile: "What Mr. Hu said is not unreasonable, but I can't do this kind of thing." I'm here today, and you should know that one is to understand the situation, and the other is to upload and release. What do you have to say. Whatever conditions you want to mention, you can tell me. As for me, I can't be the master now, but I will definitely convey your words to the chief as they are. ”

Hu Wenhai nodded, he didn't plan to get an answer from Secretary Lu.

First show your attitude and strength, and then wait for your superiors to coordinate the division of interests within the system.

Wait for them to re-determine the distribution plan of the cake.

It is the wisest choice to take away the piece that belongs to you comfortably.

"That's good, too. ”

Hu Wenhai groaned, and then said: "Xinke has never been a one-man enterprise, the core part of the new technology can be provided by me, raw material assembly, product packaging and sales, I can let it out." My only request. That is, the state can ensure the legitimate and legal patent rights of Xinke. Unless authorized by ST, other domestic enterprises shall not produce new technology products, and the infringing products shall not enter the product directory of the State Grid. ”

Secretary Lu raised his eyebrows, what he saw and heard in Xiucheng during this period of time was indeed as Hu Wenhai said, although the status of the new technology company was transcendent, it was not too greedy, but he was well versed in the way of dealing with the world.

Most of the cooperation with other enterprises is to provide key technologies, and then let the partner to produce the final product, and itself is firmly in the upstream of the industrial chain.

In this way, it is much better than the situation imagined by Secretary Lu after all.

Since there is still a bite of rice to eat, it is much easier to divide the cake on top.

Secretary Lu nodded, and said with a straight face: "Mr. Hu can have such a consciousness, I think the chief will be very happy." ”

Chapter 240 CS Secretary Lu left with Hu Wenhai's words, but Hu Wenhai still had a lot of troublesome things to scratch his head about.

In the matter of the shares of IBM in the United States, Japan is about to hold square talks, introduce Mirage fighters from Pakistan, prepare to take over the Spey engine project, and think about how to find money for the Navy...... It's all "big deals"

, the "little things" within ST

There are endless counts, and there will always be a huge amount of work waiting for him to deal with.

However, Mr. Hu is a "total"

not to mention that there are many talents, at least they will not be unable to catch the heads of the people who do the work.

After arranging the things at hand into categories, Hu Wenhai's mind opened up again.

Busy, too busy!

In the past year, he has been so busy that he has not even taken a breath.

As a reborn person who was full of regrets because he was busy with work before he was reborn, Hu Wenhai felt that his life could not be lived like this.

If it is said that making money in a reborn life is to survive and live, then what is the purpose of making money in this life?

Survival and life have not been a problem for a long time, Hu Wenhai thinks about it, and it boils down to that sentence - self-realization.

Do what you want to do, that's the true meaning of making money.

You can't be happy when you have no money after being reborn in this life, but you don't have to play when you have money, right?

Life is endless, and the toss is endless.

Taking advantage of the orderly promotion of various work, Hu Wenhai felt that he could relax a little.

As for what to play.

It's not, he's already thought about it.

"Yes, the laser receiver is connected to the smoke generator. Heck, let's just do an experiment, you can just tie the laser emitter directly with tape, and then calibrate it when the product is actually released. ”

"Okay, no? Okay, no?"

“OK！”

"Check the transmit power, don't be in danger!"

"The readiness of the units to report is good. Director Bai, start the test!"

White Stone.

Hu Wenhai's mother Xiao Yeqin's colleague in the 64th Institute, with his help, Hu Wenhai took out the first pot of gold red dot sight.

Since then, he has always been the backbone of ST's R&D team, participating in the research and development of laser guidance and unmanned aerial vehicles, and has considerable experience in invention and manufacturing.

No, whenever Hu Wenhai has any fresh ideas, the first thing that comes to mind must be him.

Under Hu Wenhai's shouting, the crowd around the venue was quickly emptied.

Although there is no danger in this realization, this is the current standardized process for the on-site realization.

No one knows what will happen to this kind of thing.

After all, it is better to trouble 10,000 times than to accidentally get hit once.

Shiraishi was the first executor, and he was held with an automatic rifle with a flashlight-style laser transmitter tied to the tip of the gun with duct tape tied to it, and a wire connected to the bolt.

"Ready!"

The laser emitter prompt light in Baishikou turned green, and he hurriedly shouted.

"Fire!"

Papapa--Bai Shi pulled the trigger again and again, and the Bayi bar in his hand let out a loud gunshot, and three bullet casings emitting gunsmoke were thrown out.

However, none of the staff present were too worried.

Because the gun was loaded with empty cartridges for exercises, just listening to the sound of gunpowder smoke was actually not lethal.

On the opposite side of the test site, three chest targets were erected in the direction of the aiming of the Shiraishi end gun, and the three targets were located at a distance of 1,150 and 200 meters respectively.

Just after Shiraishi pulled the trigger and fired the empty cartridge, colored smoke rose from the chest target opposite.

Apparently.

It is impossible for the power of an empty pack to reach a distance of one or two hundred meters.

If you change to a Chinese in the nineties, you can almost think about what this thing is at a glance.

Laser countermeasure maneuver system, or in the civil it has a "common name"

, CS field equipment.

Tong guò laser simulation battle, which in China in the future is a popular game all over the country.

This kind of game is simple and usually consists of a set of receiving devices and a set of transmitting devices.

On the premise of laser head technology.

For Hu Wenhai, there is no difficulty, it is basically a matter of engineering assembly.

With the foundation of a former military factory like the 501 Factory, a similar system can be changed in minutes.

Laser transmitters and receivers do not need to be as complex and high-power as missiles and laser irradiation guidance, and at a distance of one or two hundred meters, the power provided by two water lithium batteries can meet the needs of more than 24 hours of use.

In terms of cost, Xinke has reached a cooperation with Xiucheng Quartz Products Factory to help it introduce the manufacturing process of yttrium aluminum garnet crystals, and other supporting equipment of laser emitters can also find cooperative suppliers in Xiucheng.

The only trouble is the laser receiver and the judgment and control procedures, but fortunately it doesn't take a few bucks to import this thing in the United States.

When the wafer factory is built, it can quickly achieve the price of cabbage.

As the smoke canister received the signal from the laser receiver and smoked, a warm applause suddenly rang out on the test site.

Another new product has been invented, and whether it will be welcomed by the market in the future or not, is always something to celebrate.

Hu Wenhai rolled his eyes and beckoned to Wang Ye and Qin Kai with a smile.

To say that among the people around him, it is really the two of them who have the highest combat effectiveness.

"Next, let's do a combat test, the two of you shoot at each other in motion, can you effectively stimulate the working signal of the laser receiver?"

"Mr. Hu made this thing well!"

Wang Ye and Qin Kai are different, he has stayed in the company below, although he is a person from the air division, he has also experienced several exercises.

Oh no.

This year's domestic exercises may be called acting.

The purpose is not to develop practical experience and identify problems.

Rather, it is mainly used as a platform for familiarizing yourself with equipment coordination and technical and tactical drills.

From a military point of view, the exercises at this time can be regarded as purely planning-centered.

Before the exercise, the "script" was made

, and then every move in the exercise was carried out according to the script.

In addition to military ideological and traditional reasons, technical factors also restrict the actual combat and confrontational nature of the exercise.

After all, if you want to conduct an actual combat exercise, you can't really put a gun on the "enemy" in the exercise

out, right?

The traditional exercises, which are estimated according to the actual situation, are simply unable to adapt to the complex evolution of the battlefield brought about by the progress of military science and technology.

The result is a drill that has been criticized for not being used to turn into acting.

Wearing this set of exercise equipment, Wang Ye felt its benefits.

It's the simplest.

Your marksmanship is not good, and if you can't hit, you won't miss!

That is, with such exercise equipment.

Only the advantages of elite troops can be truly brought into play.

Otherwise, an ordinary infantry company encounters a reconnaissance company, and as a result, both sides suffer heavy losses according to an estimate of their strength, with the same strength of both sides.

With this system, the value of elite fighters in the exercise can be reflected.

Wang Ye and Qin Kai didn't say a word, and with the help of the staff, they put on a complete set of laser countermeasure equipment.

Next to the helmet is a smoke canister.

There are laser receivers on the front and back of the body, and the Bayi Bar rifle has been modified to trigger a laser launch when an empty bullet is fired.

However, Hu Wenhai has only played civilian-level CS confrontation in the future, and I don't know if this thing in his cottage can meet the needs of military exercises.

Since it was a real combat exercise, it could not be carried out at the test site in Pingchuan.

Hu Wenhai led the team, and everyone turned their heads and drove towards the empty factory building where the original 501 factory was abandoned.

The new technology factory has been renovated, expanded and newly built, and four of the original seven workshops have been abandoned.

Three more have undergone some renovation and expansion and have been put back into use, and a few new ones have been added quite "luxury"

of the steel structure workshop.

Three of the abandoned workshops were demolished and re-planned, and one workshop was temporarily demolished, and then it was quickly stopped by Hu Wenhai.

His little careful guessing was nothing more than a layer of skin left over from the original 501 factory.

With this workshop, the 501 factory still exists.

ST can be transformed into a "state-owned enterprise" at any time

of the skin.

Although we all know what is going on with Factory 501 and Xinke Company, many times there is no such skin, after all, it is still different.

Dressed up, Wang Ye and Qin Kai entered the venue from two directions respectively, and after a while, they heard the sound of gunshots like popping beans.

The two were worthy of being elite soldiers, and they fought for more than ten minutes.

I only heard the gunshots, but I didn't see the smoke coming out of the smoke generator at all.

"Huh, isn't there a problem with the equipment?"

Hu Wenhai wondered, beckoned people to take out another set of equipment: "Put it on for me too, I'll test it myself, isn't it bad in actual combat?"

In the final analysis, it was Hu Wenhaiye and Qin Kai who were "having fun" in the abandoned factory

, he couldn't help but have some itchy hands.

asked people to equip themselves with a set of confrontation equipment, and Hu Wenhai happily rushed into the ruins of the workshop.

Then, in less than half a minute, he crawled out of the workshop.

"No more playing, no more playing!"

Hu Wenhai snorted with a red smoke canister on his head, and said hatefully: "I'm your boss, please take care of my mood, okay?"

Behind him, Wang Ye and Qin Kai looked at each other and shrugged innocently.

In any case, at least it shows that laser countermeasures can still operate in real combat, which is gratifying, right?

Without waiting for Hu Wenhai to complain, a series of military vehicles drove over in the distance.

The soldiers jumped out of the car, and a fat man, who looked like a mountain, jumped out of the passenger seat of the head car.

Hu Wenhai, who took off his sunglasses and was still smoking red smoke from the bag, couldn't help laughing: "What are you playing with Mr. Hu?
