Listen to more virtual currency, virtual reality, virtual host... Have you ever heard of virtual growth? "To grow high-quality silicon carbide (SiC), we need to design, debug and optimize the production process." Professor Chen Xiufang, a professor at the State Key Laboratory of Crystal Materials, has an important task - growing by physical vapor deposition. High quality, large size SiC single crystal material. "But the actual growth time, material consumption, and may be unstable, through the computer simulation of 'virtual growth' process, can be informed in advance of temperature, growth rate and other information," said Chen Xiufang. This method works just like the "war-inducing system" and actual combat. Recently, the National Key R&D Program “Low- and Medium-voltage SiC Material Devices and Their Application in Electric Vehicle Charging Devices†held a mid-year summary meeting. The project undertaken by the Shandong University and other organizations achieved low levels in just one year. Impurity 6-inch SiC crystals, single-crystal diameter larger than 15 cm, in order to allow these wafers to mass production, the research group also built a 6-inch SiC single crystal furnace with independent intellectual property rights. The project leader and a professor from Zhejiang University introduced the project. Taking the application requirements as the traction, the project will realize the full industry chain innovation of materials-chip-module-charging device-demonstration applications. In other words, high-quality SiC materials and chips will become the core components of the charging equipment. After packaging, design, and other processes, the electric vehicles will be filled with electricity in an efficient and high-energy manner. “The project team is composed of a number of stronger units in each segment of the SiC field. Up to now, the second subject has developed 650V and 1200V SiC MOSFET chips. The third subject has carried out research on cutting-edge high-K gate dielectric technology and developed 1700V SiC MOSFET chip, subject four completed the trial production of the full SiC half-bridge power module, subject five have two charging prototypes in Beijing trial operation.†The grand occasion told reporters that the five task groups are like five joints in an industrial chain, Supporting each other and supporting each other, they will present the entire chain of SiC from materials to the industry. "In the second half of this year, Topic I will supply the suppliers of Topics II and III, and initially complete the chip package and module design." In the grand task file, there is a colorful dot chart, time node and task Head-to-head, tail-tail, parallel progress, and orderly completion. The project even formulated "send plans and standards for projects between upstream and downstream projects." “Every time they are rushed together to solve problems.†Pompano said that the previous year's research is progressing steadily. What we need to do at this stage is to overcome core technologies in a clear direction and further implement key tasks. If the whole project is a large ship that is driving to the “new type of charging method,†the subject is the helmsman on this ship. “It clearly puts forward application requirements and achieves goals, while the upstream and midstream R&D team develops specific advancing plans around goals. "Pompous said. As one of the specific implementers who landed, Tyco Tianrun Semiconductor Technology (Beijing) Co., Ltd. Wu Hailei told the Science and Technology Daily reporter, “Compared with the current charging piles, the new SiC charging module can achieve a maximum conversion efficiency of 96%.†High temperature environment and no-load are the "pain points" of traditional charging piles. The application of third-generation semiconductors will solve this problem. Wu Hailei said that studies have shown that when the operating temperature of the traditional SiC device charging module reaches 55°C, it starts to reduce power output or shutdown, and the new SiC charging module starts to reduce the power output at 65°C. "This basically eliminates the summer time machine. Case." The "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)" shows that by 2020, the cumulative production and sales volume of pure electric vehicles and plug-in hybrid vehicles will exceed 5 million, "which means that 4.8 million distributions need to be built. Charging piles, 12,000 centralized charging and exchanging power stations." Wu Yalei said. This is an industry that combines continuous expansion and continuous improvement. It is a major adjustment of energy structure and a revolutionary subversion of new energy to fossil energy. Its starting point is the growth of a perfect crystal called SiC, followed by It is an industry chain with strict layout and innovation.
