“…9 (b) and (c). In this case, the fielddistribution trend is different from static WPT [5], [24] results mentioned in Subsection V.B, as well as that of shown in Figure 9 (a). In this case, the peak EM-field spot is adjacent to the ground-side coil center, instead of a vehicle-side coil center in the middle.…”

Dynamic wireless charging of electric vehicles (EV) is an emerging charging technology to enable non-contact wireless charging while the vehicle is moving. Compared to stationary wireless charging, in-motion wireless charging involves dynamic processes in which an EV is passing over the charging pads (transmitters). This in-motion process makes the dynamic electromagnetic (EM) environment more complicated, and EM safety needs to be ensured under all circumstances. This is due to the fact that the entire vehicle body may be exposed to magnetic fields while the vehicle moves over the energized transmitter. This paper investigates several typical charging scenarios when EVs approach, pass over, and move away from the charging pads. Quasi-dynamic models, which are preliminarily verified by coils' inductance measurements, are developed to analyze the dynamic process. Based on the quasidynamic analysis, shielding solutions are also studied to ensure EM safety for the dynamic wireless charging processes.

“…Another charging technology that will allow autonomous vehicles is wireless charging [41], after all, if someone must plug the vehicles in, they cannot be considered completely autonomous. There is also dynamic or in-motion wireless charging which, together with autonomous static charging, potentially allows vehicles to have unlimited range eliminating the range anxiety of electric vehicles [42][43].…”

“…The feasibility of this system resulted in the team looking into 300 kW static wireless charging systems and 200 kW dynamic wireless charging systems. Static wireless charging at home or work brings the same concerns about connection to grid [41]. With vehicles being charged from the road dynamically, in addition to the all the electronics mentioned earlier with respect to autonomous vehicles, high power, a medium voltage connected power electronics system will be a part of the traffic system connecting roads directly to the grid.…”

In this paper, a broad overview of the current research trends in power-electronic innovations in cyberphysical systems (CPSs) is presented. The recent advances in semiconductor device technologies, control architectures, and communication methodologies have enabled researchers to develop integrated smart CPSs that can cater to the emerging requirements of smart grids, renewable energy, electric vehicles, trains, ships, internet of things (IoTs), etc. The topics presented in this paper include novel power-distribution architectures, protection techniques considering large renewable integration in smart grids, wireless charging in electric vehicles, simultaneous power and information transmission, multi-hop network-based coordination, power technologies for renewable energy and smart transformer, CPS reliability, transactive smart railway grid, and real-time simulation of shipboard power systems. It is anticipated that the research trends presented in this paper will provide a timely and useful overview to the power-electronics researchers with broad applications in CPSs.

“…For the half bridge inverter in Figure 2.14 (a), with Q1 ON and Q2 OFF, the inverter output is connected to Vin, while, with Q2 ON and Q1 OFF, the inverter output is short-circuited and becomes zero. Therefore, as shown in Generally, SiC devices are suitable for high power applications [9,51,52], while GaN devices are expected to increase system power density. For example, the half-bridge evaluation board EPC9048C [53], which is based on the GaN device EPC2034C [54],…”
