Although many companies in the United States have entered the coal-to-hydrogen project, the technology of processing hydrogen into hydrogen fuel and hydrogen fuel catalytic converters is in the hands of Huaxing Group, and it is the best.

Yang Jie was also called to the central government to accept the inquiries of these central bigwigs because of the US side's suppression of Huayuan Group Company and Prager Energy Group Company.

This year, Huaxia has exported nearly $13 billion in exports to the United States alone, and more than 80 percent of this money has been left in China, and has become Huaxia's fist product.

Moreover, the procurement volume of several European countries is also rising rapidly, and the central government also attaches great importance to this.

After learning that Yang Jie had closed Prager Energy Company and sold some businesses to some companies in the United States, the plan of the United States to join hands to strangle Prager Energy Company was frustrated, Song Xinyang and Zeng Jiabao and other bigwigs nodded one after another.

"You still have some business in the United States, so you must be affected to a certain extent, right?" Song Xinyang asked.

"We are already prepared for this internally, and we will plan for the next few years to make a plan for the replacement step by step, so that when they attack us again, it will not deal a fatal blow to these businesses. ”

"The Pioneer Energy Group is now part of the Huaxing Group, and this company must not be able to close down like Prager Energy, right?"

"Pioneer Energy Group is a public utility company that is related to some natural gas and electric services in California and other states, and is closely related to the local economy and people's lives. ”

Song Xinyang nodded, he looked at Yang Jie and said, " The domestic situation is quite different from that of the United States, and now the demand for electricity in the coastal areas of the country is very tight, and the power in the central and western regions needs to be transmitted to the coastal areas, which requires ultra-high voltage transmission projects, before these ultra-high voltage core technologies are in the hands of Siemens and Absey Brown Swiss Group and Alstom, I heard that you have mastered the 6500V level of high-voltage insulated gate bipolar transistor technology, and have built an 800 thousand volt UHV converter valve in the ultra-high voltage laboratory?

"Yes, with the help of Ximenkang, we have developed gallium nitride high-power modules, and also mastered cheaper silicon carbide high-power modules, so these high-power modules are smaller in size, lower in energy consumption, lower in switching power consumption, and the assembled converter valve is a foreign similar product The volume has been reduced to one-third, and the converter valve built by building blocks weighs 70 tons, and now we can do less than 20 tons. ”

Yang Jie said with a smile.

Simonkang has been continuously researching and developing silicon carbide technology, and it is at the same level as Siemens in terms of technology.

Since the acquisition of Ximenkang, Yang Jie has also increased the research and development of silicon carbide technology, and established a silicon carbide production line in Huaxia, at the same time, Ximenkang's engineers are also involved in the design, development and production of gallium nitride power devices, which has greatly accelerated the research and development progress of Huaxing Group in this regard.

Yang Jie is also the first in the ultra-high pressure laboratory to build a silicon carbide and gallium nitride power module converter valve for various test tests, the test results show that the performance of these two converter valves in all aspects has been greatly improved, compared with gallium nitride, silicon carbide is cheaper in cost, and now Huaxing Group has reduced the cost to a level close to gallium arsenide.

This is mainly due to the fact that Ximenkang has a very good technical foundation in the preparation of silicon carbide materials, and the design level of process and power devices is very high, which also allows Huaxing Group to take a big advantage in this regard.

Of course, Huaxing Group has also invested a lot of manpower, material and financial resources in this regard, and has carried out continuous research and development on the basis of Ximenkang's technology, and has also cultivated a very strong technical team.

The company's revenue has risen rapidly from more than 200 million US dollars to more than 3 billion US dollars, and the revenue has increased more than 10 times, and has become a technology giant company in the field of power devices, and also firmly occupies the top spot in the domestic power device market share.

This is mainly due to the explosion of Huaxia's production capacity in communications, fuel cell industry, automotive electronics, and consumer electronics.

There are very few things in China that know that Ximenkang Company is a subsidiary of Huaxing Group Company, but people in the circle know it.

Before Zhu Ronghua put a burden on Huaxing Group to ask Yang Jie's company to undertake the research and development project of ultra-high voltage flexible DC transmission, Yang Jie naturally did not dare to slack off.

The laboratory has also mastered several key technologies of ultra-high voltage transmission projects, including the core equipment of DC transmission projects such as converter valves and DC cable technology.

This laboratory is a joint venture between Huaxing Group and the State Grid Corporation, and the State Grid has also dispatched dozens of technical experts in this area to participate in this project, and Huaxing Group has also dispatched the same number of technical personnel to participate.

This project also makes use of a large number of mature technology and the technology of domestic research institutions, Huaxing Group provides silicon carbide and gallium nitride thyristors and thyristor control units for this project, including the core components such as damping capacitors, equalizing capacitors, damping resistors, equalizing resistors, saturation reactors and other units designed and developed by domestic research institutions, and then produced by the component factories of these domestic military enterprises.

Previously, Yang Jie worked hard to get a lot of Japanese component technical data and production equipment back to China from the Philippines, which also improved the technical level of domestic military components a lot.

In recent years, Huaxing Group has also purchased a large number of components from these domestic enterprises, which has also allowed these domestic component companies to maintain sufficient profits, and also has funds to engage in research and development, and has caught up with the technical level of the Japanese in almost seven years.

This also ensures that the quality of the converter valve built in the laboratory is still very reliable, and 80% of the converter valve uses domestic components.

These parts purchased from abroad are mature products from abroad, the price is very low and will not be blocked, in order to reduce the cost of natural procurement from abroad.

In addition, the water-cooled radiator required by the thyristor, the core component of the converter valve, not only dissipates heat for the thyristor, but also acts as a pressure bearing for structural parts, conducts electricity, and has a lifelong warranty, and the quality requirements are extremely strict, making this water-cooled radiator the top product of water-cooled radiator in the power electronics industry.

After the R&D team designed it, they also negotiated with overseas companies, but these companies were also reluctant to accept this order because of their small output, or they were asking for a sky-high price.

Subsequently, the Machine Tool Research Institute also undertook this task and produced this set of water cooling system.

Now the machine tool research institute is responsible for the design, development and production of various high-precision machinery and equipment products of Huaxing Group Company, anyway, the research institute is not short of money, so it is hard to tinker with some special equipment and products, many instruments and equipment in the laboratory are also designed by the instrument and equipment research and development team of Huaxing Group Company, and then handed over to the machine tool research institute to produce and manufacture, but also to ensure the research and development progress of the ultra-high pressure laboratory.

With these supports, the R&D team can also concentrate on the research on the high-potential overall shielding and shielding performance of the converter valve, the control and suppression technology of the partial discharge level, the integration of the cooling, control and pressure equalization technology of the converter valve, and the research on the type of the converter valve.

In addition, the R&D team also used the research technology of Huaxing Group in cross-linked polyethylene insulation materials to successfully develop the first ± 525kV flexible DC cable system in China.
