Delta successfully held a seminar on new technologies for electronic power

From May 23 to 25, 2019, the Delta Power Electronics Technology Application Seminar, hosted by Delta Group of Zhejiang University, was held at the KONE Hotel in Wujiang, Jiangsu. Experts and professors from all over the world in the power electronics technology industry and 360 teachers, students and industry personnel from more than 10 key universities such as Tsinghua University and Zhejiang University gathered together to conduct in-depth discussions and communication on core technologies and hot topics such as excellent power engineering transmission devices, and promote each other's development plans for aerospace, road transportation, power supply systems, intelligent manufacturing systems and other industries. During the meeting, the list of winners of 12 scientific research projects supported by the "Delta Power Electronics Technology Technology and Education Development Trend Program" was released during the meeting. Cai Xu, an expert professor of Shanghai Jiaotong University, and Wang Fei, an expert professor of Shanghai Jiaotong University, and Liang Lin, an associate professor of South China University of Technology, won the "Zhongda Young Experts and Scholars Award". The exchange meeting also invited Li Yaohua, an expert and professor from the Institute of Electric Welder Engineering of the Chinese Academy of Sciences, to introduce in detail the application of modular design multi-pulse signal SPWM in transmission, DC power supply system, large space motor drive and other industries with the issue of "modular design multi-pulse signal SPWM and application".

In his opening speech, Professor Li Zeyuan, academician of the Chinese Academy of Sciences, academician of the Chinese Academy of Engineering, academician of the United Kingdom Academy of Engineering, expressed his gratitude to Mr. Zheng Chonghua, founder and honorary boss of Delta Group, for his support and outstanding contributions to the scientific research and development trend of China's power electronics technology colleges and universities over the past 20 years. I believe that China's power electronics technology is playing a very important role in the world today, and China will play a leading role in the world in 10 years. He also expects that all the trends in new industrial production, high-tech infrastructure and power electronics will not be separated from the faculty and students here, and that energy is expected to increase to 80% of the overall electricity target by 2050. In view of the changes in the energy mix, current research on power electronics technology will focus on the development and design of renewable resource technologies. According to the total energy consumption output of power projects in the world in 2012, a 1% increase in electromagnetic energy efficiency is equivalent to saving the total annual power generation capacity of the two Three Gorges Dams (80TWH/yr); By 2050, the overall power energy requirement will increase by a factor of eight, and every 1% increase in efficiency is equivalent to saving the total power generation capacity of the 16 Three Gorges Dams. Focusing on increasing the energy consumption level by 1% should be something that can be guaranteed by the authoritative experts and scholars here within 1-2 years.

Mr. Zheng Chonghua, the founder and honorary president of Delta, paid attention to the vigorous development trend of China's power electronics discipline in the past 20 years, which is inseparable from the long-term and silent perseverance of the teachers who have made unremitting scientific research and cultivated people, as well as the students who have worked hard to study and train. Based on the key technologies of power electronics technology, Delta has continuously invested in the research and development of independent innovation products to improve the efficiency of power energy conversion and promote environmental protection, energy conservation and carbon reduction. From 2010 to 2018, Delta's high-efficiency, energy-saving, and environmentally friendly products helped customers around the world save 28.1 billion kWh of electricity while reducing 15.06 million tons of carbon emissions. Every step in the technological advancement of power electronics technology has the potential to add up to a big step in driving energy savings and consumption reduction around the world. In order to cope with increasingly pessimistic climate anomalies such as global warming, it is very necessary for everyone to continue to work hard and invest in each other's independent innovation and technology product research and development. It will bring China's power engineering electronics industry to a higher level, enter the world's leading position, and promote the concept of global sustainable development.

Delta's Chief Executive Officer and Mr. Delta's Operations Veteran also shared with everyone the development trend and reasonable layout of Delta's power electronics technology. He stressed that from the perspective of new trends, whether it is in population growth, excellent consumer electronic equipment transformation, Internet technology and other technological innovations, these have put forward great improvements to the requirements of power engineering, which means that the application of power electronics technology will be more and more. He believes that the core technology to deal with the problems of electric energy, natural environment and resources relies on the high frequency, high power consumption, high efficiency and high reliability of digital power electronics. In the future, Delta's control system will develop in four directions, including industrial production in the 10,000-kilowatt range, miniaturization of MHz modules, technology of power electronics based on new components such as carbon-carbon polymer materials (SiC) and gallium nitride (GaN), and intelligent practical operation of power electronics systems. In the development trend of the work, it is mainly the rational layout of the four major power electronics technology related manufacturing industries: transportation and mobility, the whole industrial chain of the Internet of Things (IoT), intelligent manufacturing system, system software and intelligent system, and microgrid. In addition, in terms of green energy and smart energy system software, in addition to a single component, Delta will also start from a targeted approach to improve the efficiency of power saving, so that Li Zeyuan experts and professors often say that the construction of power plants can be reduced.

Li Yaohua, an expert and professor from the Institute of Welders of the Chinese Academy of Sciences, shared the new development trend of high-power modular power supply with the guests on "modular design of multi-pulse signal SPWM and its application". Professor Li Yaohua introduced in detail the key scientific research work carried out at the level of multi-pulse signal SPWM (MMC) in the modular design of welders of the Chinese Academy of Sciences, including several innovative ability scientific research on power engineering electronic transformers, flexible DC transmission, power engineering transmission systems and their railway line power supply systems, etc., and also emphasized the problems and challenges in them; In addition, we have a future outlook to match the future development trend of MMC power supply circuits used in high-voltage power places, including components, topologies, and new application sites.

At the opening ceremony, Mr. Zheng Chonghua, the founder and honorary president of Delta, and Li Zeyuan, academician of the Chinese Academy of Sciences and academician of the Overseas Academy of Engineering, were experts and professors Cai Xu of Shanghai Jiaotong University, who won the honorary title of "Zhongda Experts and Scholars" this year, Wang Fei, and Associate Professor Liang Lin of South China University of Technology, respectively.
