IEEE Montreal Keynote Event
September 28, 2023 @ 5:30 pm - 8:00 pm
Please join us for this year IEEE Montréal Keynote Event: Plugged charging topologies have been investigated thoroughly in recent years, based on existing SAE J1772 standards for AC and DC charging. More recently, power supply/charger manufacturing companies have also been seriously looking at wireless charging as an attractive solution to avoid physical drawbacks of wired or plugged versions of charging. The high-level goal of this presentation is to focus on introducing advanced rapid charging using wireless power transfer (WPT) for autonomous (driverless) e-mobility. Both inductive power transfer (IPT) and capacitive power transfer (CPT) systems will be introduced. The major market for IPT-based wireless charging is the mass transit industry, such as electric trains, buses, and trams, in the range of 100-250 kW, while both IPT and CPT could be used for charging small utility-grade EVs (golf carts, scooters, etc.), in smaller sizes of ~1.0 kW. Critical issues such as IPT coil design, CPT dielectric medium/transfer plate designs, and converter topologies will be discussed. Detailed results of finite element analysis (FEA) designs for coils will be presented. The design of charger topologies on the secondary side will also be discussed. The challenge is to come up with 1-stage power conversion, including high-frequency (HF) AC/DC rectification and DC/DC charger functionalities, with conversion efficiencies of ≥ 98%.
