Title:Millimeter-wave Transceiver Chips with Antenna in Package Abstract: The increasing high requirements of wireless communications and sensors are making research and commercialization of millimeter-wave integrated circuits and antennas experience tremendous growth. The advancement of modern CMOS technology facilitates it to become the prevailing technology to achieve low-cost and highly-integrated millimeter-wave integrated circuits. Meanwhile, the compound semiconductor is still a must for low noise and high power millimeter-wave system. As the operating frequency enters the millimeter-wave regime, the circuit component's size becomes comparable to the electromagnetic wave wavelength. Therefore, a mixed design methodology using both the lumped and distributed elements in the millimeter-wave integrated circuit design is of great interest, not only compound semiconductor but also CMOS integrated circuits. On one hand, to achieve high-integration and high-pwerformance, the heterogeneous packaging architecture to combined the merits of both CMOS and compound semiconductor millimeter-wave integrated circits is becoming an attractive technology. On the other hand, considering the efficiency, cost, and integration of advanced wireless systems, discrete antenna is no longer suitable for millimeter-wave wireless systems. Therefore, antenna-in-package (AiP) has become the mainstream for millimeter-wave system, which implements an antenna or antennas on (or in) package of chips leading to a high efficiency and highly-integrated radio. In the talk, innovative design approaches and methodologies on millimeter-wave integrated circuits，subsystems and corresponding antenna-in-package will be introduced. |  |

Title: Establishment of three-dimensional digital twin model of UHV converter transformer equipment based on image data processing and optimization design of its accessory structure Abstract：Taking the converter transformer for UHV converter valve hall as the research object, this special speech discusses the construction process of its three-dimensional digital model from the insulation structure of the transformer body. Further, focusing on the outgoing device and bushing structure of converter transformer, this paper introduces the typical structure, the actual valve hall operation environment and the heating theoretical model of high-voltage power equipment under high harmonic load from the perspective of high-voltage power equipment operation, analyzes the electro-thermal coupling nonlinear electric field of transformer outgoing device, and optimizes its insulation structure by using RBF neural network and NSGA-II multi-objective optimization algorithm. Considering the complex structure of converter transformer and its outgoing line device and converter bushing area are important typical accessories, this paper focuses on the construction of digital twin 3D model in this area, and carries out on-site operation and maintenance simulation test and high current Functional response analysis under high voltage load. The digital twin model of the outlet device area is constructed according to the electro-thermal coupling physical field simulation model. The electro-thermal sensor is used to monitor the on-line voltage and current waveform in real time, and the interaction between the on-site operating parameters and the loading data of the digital twin model is realized. On the other hand, the intelligent extraction and identification of material area in the digital twin model is realized, and the material parameter performance can be changed according to the physical field environment, so as to adapt to the structural design and performance evaluation of different operating environments. Furthermore, in order to analyze the relationship between the internal transient temperature of the converter bushing and its short-time current carrying capacity and long-term aging performance, an evaluation process method of the long-term internal insulation performance of the high-voltage bushing is proposed. Focuses on the 3D construction of digital twin model in the outgoing area of converter transformer. Its research method can be extended to key components such as converter body winding structure, oil paper insulation area and on load switch. The research results of this paper can provide theoretical guidance and technical reference for the insulation structure design of converter transformer body, especially for the structural design and operation maintenance of outlet device area, and can provide some theoretical guidance for on-line analysis of short-term current carrying capacity and long-term aging performance of converter transformer outlet device area. |
