Amorphous and nanocrystalline alloy materials are used to support the development of power electron.
On October 15, the 18th session of Beijing science and technology exchange activities on academic power electronic technology exchange in antai technology of amorphous metal division meeting room, meeting of amorphous and nanocrystalline soft magnetic alloy material support power electronic technology development are discussed, from zhejiang university, Beijing institute of technology, the northern industrial university, Beijing superfamily group co., LTD., metallurgical automation research and design institute, Beijing gold since it was intelligent control co., LTD., inbev electrical appliances professors and industry experts participating units, amorphous metal department related to leadership and technical backbone of more than 50 people attended the communication conference. The meeting hosted by the power electronic technology, amorphous metal division to undertake, communication meeting shall be presided over by Zhou Yaning secretary of Beijing power electronics association, Beijing power electronics society chong-jian li of zhi-chao lu, amorphous metal division general manager welcome speech respectively.
Chong-jian li, chairman of the proposed, current towards to the high power and high frequency power electronic, around the high power and high frequency power supply held several times about the SiC semiconductor materials such as workshop, the surrounding power efficient magnetic device with soft magnetic materials, special discussion also is the first time; Zhi-chao lu is amorphous, general manager of nanocrystalline materials both at home and abroad industry antai technology of amorphous and nanocrystalline industry status quo of development are introduced, and emphasis on the development of high precision amorphous nanocrystalline materials and industry development is also in order to match the development of power electronic high power and high frequency requirements.
Amorphous metal division yongfeng nanocrystalline products branch general manager Dr David law first do the topic of the amorphous and nanocrystalline soft magnetic alloy material industry present situation and the development trends of the report. From antai technology of amorphous industry overview, amorphous nanocrystalline soft magnetic alloy material technology base and related standards, amorphous and nanocrystalline soft magnetic alloy material problems and trend of development of three aspects such as the speech. Later, the northern industrial university associate professor Jiang Zhengrong, yongfeng guang-min li, vice minister of nanocrystalline products branch market technology product development department, market technology vice minister Dr Wang Xiang guangdong Huang Xiao et from amorphous and nanocrystalline magnetic devices, advanced magnetic material in reverse characteristics of controllable reactor and transformer, amorphous and nanocrystalline magnetic powder core, nanocrystalline soft magnetic alloys in such aspects as the application of high precision measuring transformer made special reports.
After the seminar, the experts, scholars, entrepreneurs, and a member of the power electronics society accompanied by the leadership of the group visited the department of rooms, laboratories and production workshop, fully understand the amorphous metal division of research and development strength and production capacity. Yongfeng products branch general manager David law by amorphous nanocrystalline materials is introduced, the technology level of iron core and related devices and application case situation, for the company's production of magnetic materials and everyone is very interested in, and said that further development of energy-saving new materials to the development of power electronics is also a powerful drive. In the production workshop, and for the first time you zero distance contact large-scale nanocrystalline materials production site, to see the different shape and size of the nanocrystalline varnished curing core and cutting iron core, and ask for details of the core temperature and the use of reliability, David law expounded for everybody, general manager of nanocrystalline iron core is used as the high frequency transformer silicon steel, ferrite, relative to the market of integrated design technology advantage, in view of the design selection and the problems that arise when the normal operation of the power supply and experts are discussed and analyzed. In the LABS of the institute, the question of the magnetic parameters encountered in the design of the power supply was obtained. They not only saw how common magnetic parameters test, also know to by material research and development and the heat treatment process can change some magnetic parameters, which meet the demand of the inductance in the design of power supply and impedance. In the test workshop and the device engineering laboratory, we observe and discuss it warmly. The atmosphere is quite lively. EMI lab, especially to see the ongoing frequency conversion air conditioning EMI test different schemes of amorphous and nanocrystalline materials common-mode inductor and PFC inductor, experts and scholars are interested in, and watched the EMI test curve, and with the testers and the limits of the curve in improving schemes are discussed. Finally we saw the welding machine with high frequency transformer production line and online product, witnessed the high precision of nanocrystalline materials in case of the successful application of high frequency transformer, more determine the reliability of the amorphous nanocrystalline materials applications.
Immediately after the visit, the automation of experts on the special discussion with division of technical staff, they said the significance of this meeting is not only let us have further understanding of amorphous material, and let everybody has the specific application of amorphous materials also intuitive cognition, they will be in amorphous nanocrystalline materials in the design and application of high frequency power supply development phase further negotiate with the company.
