Speech Title: Application of wireless power transfer in electric aircraft, railway, ships, and road vehicles
Abstract: Wireless power transfer (WPT) technology offers significant improvement in convenience and safety and has found many applications, such as electric vehicle (EV), implanted medical devices, mobile devises, under water vehicles, industrial automation equipment, robots, and automatic guided vehicles, etc. Both capacitive and inductive wireless power transfer technologies have been investigated for various applications. Experiments have shown that tens or even hundreds of kilowatts of power can be transferred over 200 mm distance with an efficiency of 97% (DC-DC) or more, and an alignment tolerance of up to 300mm.
In this presentation, we will first look at the basic principle of WPT. Then we will show that safety is still one of the major concerns of WPT system for both inductive and capacitive power transfer, especially for high-power applications. Then, we will discuss two unique topologies developed by the research group of Prof. Mi, including the double-sided LCC topology and the LCLC topology for capacitive wireless power transfer. Finally, we will show some case studies that involve electric aircraft, railway, ships, and road vehicles.

Speech Title: Challenge to Realization of 99.9% Power Conversion Efficiency Inverter and Its Application Fields
Abstract: With the advent of wide-band-gap(WBG) power semiconductor devices, power conversion with high conversion efficiency has become possible, but since the output of DC-AC power conversion (inverter) is AC, it is more difficult to achieve ultra-high efficiency compared to DC-DC conversion.
First, the current status of recent published literature on high efficiency inverters is presented, followed by the latest results of high efficiency HEECS inverters being pursued by the authors' group. With higher efficiency comes the need to guarantee the accuracy of the measurement. Second, speaker’s group have proposed a new loss measurement method called the VTASLM, which uses only electrical measuring instruments, and have measured a conversion efficiency of 99.75% with a measurement accuracy of 0.006%. The measurement method and results are presented. Third, the measurement results of the loss breakdown are presented and the policy on how to obtain higher efficiency is discussed. Finally, the speaker's dream is discussed concerning a future power grid that makes effective use of renewable energies using high-efficiency power converters.

Speech Title: EV Charging : Technical Challenges
Abstract: Electric vehicles (EVs) reduce air pollution and global warming, and are ideal for sustainable living. However, the high uptake of EVs also poses some technical challenges. These include the demand for increased levels of EV charging infrastructure, demand-side issues associated with charging infrastructure planning and charging services, and grid impacts due to large-scale charging demands that compromise the stable and economic operation of the power grid. Thus, to mitigate grid impacts and overcome demand-side, it is crucial to deploy charging infrastructure strategically and operate charging services properly. This seminar discusses these challenges, clarifying the technical problems, and presents the solutions that have been proposed. The seminar concludes with new research directions in this area to promote further research.
