Title of Speech: Advances and Applications in Capacitive Wireless Power Transfer Technology 

Abstract: Wireless Power Transfer (WPT) technology, due to its safety, intelligence, and convenience, is highly suitable for applications in fields such as electric vehicles, rail transit, electric ships, consumer electronics, and biomedicine. In recent years, WPT has made significant advancements, becoming a hot research topic. Capacitive Power Transfer (CPT) is an important branch of WPT. It operates by utilizing capacitive coupling through high-frequency electric fields to generate displacement currents in the dielectric, thereby transferring power. Compared to other technologies, CPT offers advantages such as lightweight design, low cost, and resistance to interference from metal objects. Initially constrained by the low permittivity of air, early CPT implementations were considered capable only of transmitting small powers over distances of a few millimeters. However, through years of development, CPT has demonstrated capabilities for effective transmission over distances around 100 mm, achieving power levels in the kilowatt range with efficiencies exceeding 90%. This makes it a promising solution for high-power charging applications, such as electric vehicles and electric ships. This report introduces the research progress of CPT technology, with a focus on power and efficiency improvement techniques, as well as its application in various environments.

Title of Speech: Advanced Key Theory and Technology for DC Breaking  

Abstract: Under the development trend of global clean energy and environmental protection, the installed capacity of new energy power generation such as photovoltaic power generation has maintained a rapid growth. Energy storage systems has also been vigorously developed. At the same time, higher requirements have been put forward for DC circuit breakers that play a protective and control role in the new energy power generation system. In the photovoltaic power generation system and storage systems, the circuit breaker is required to be able to break the DC short circuit current of higher voltage (DC 2000V) and larger current. Based on, the research group has carried out simulation and experimental research on DC arc characteristics. Based on the simulation, the high-efficiency arc breaking technology is put forward. Through the matching design of structural parameters of arc extinguishing chamber, the arc dynamic characteristics can be coordinated regulation. Furthermore, for the direct current interruption at higher voltages, a magnetic-integrated hybrid direct current circuit breaker topology was proposed. By combining mechanical switches with power electronic devices, it successfully achieved direct current interruption at higher voltages and larger currents. This helps to promote the healthy development of the new energy system.
