Urban autonomous electric mobility (e-mobility) and electric mass transit are being realized quickly. They are the dire need for populous metropolitan cities. In addition, urban mass transit (buses, subways, and trams), among other modes of urban transportation, are a major challenge facing cities. In several overcrowded cities around the world, existing urban mobility systems are simply inadequate. Harmful emissions, accidents, knotty congestions, and unscheduled operations are just among the critical few issues that are creating transportation chaos worldwide. Autonomous and driverless e-mobility will certainly alleviate such disruptions. These new modes of urban e-mobility will be smart and free of human error. The key ingredient to build a sustainable and efficient autonomous mobility infrastructure will most certainly include electrified transportation. Opportunistic static charging and dynamic, in-motion charging of urban autonomous e-mobility and mass e-transport, powered either by high-energy batteries or high-power ultracapacitors, will be the need of the hour. Novel power electronic conversion systems and innovative coil designs will play a major role in interfacing high-energy/high-power electric storage systems to the charging infrastructure. The proposed NSERC DG program specifically address the above issues comprehensively, focusing on the design of universal, wide-ranging wireless fast charging infrastructures. Both static (opportunity charging) as well as in-motion (dynamic charging) systems will be designed, developed, tested, and verified. Wireless Power Transfer (WPT) can be essentially classified into two methodologies: Inductive Power Transfer (IPT) and Capacitive Power Transfer (CPT). IPT is the more established method, while CPT is an emerging approach, catering solely to low-power levels at the moment (up to 1.0 kW). The proposed NSERC DG program will aim to address several key challenges in advancing the state-of-the-art for both WPT methods. The specific focus of this proposal is high power, high-efficiency static and in-motion fast charging for future modes of urban autonomous e-mobility and mass electric transportation from e-bikes to e-buses. WPT charger ratings ranging from 1.0 kW to 50.0 kW will be investigated. The overall program is divided in to 6 major tasks: 1) IPT magnetics (coil) design; 2) Novel WPT power electronic converter designs; 3) Advanced WPT controller development; 4) Design of an in-motion (dynamic) opportunity fast charger (50 kW); 5) Capacitance design for CPT; hybrid IPT/CPT design; and 6) EMI shielding. The above exclusive research targets make the proposed program particularly unique and specialized. This research will most definitely lead to future progress, more specifically, with regards to overall efficiency and performance improvement of autonomous e-mobility/e-transportation infrastructure.

城市自动驾驶（E-Obility）和电力大众运输迅速实现。他们是人口大都市的迫切需要。此外，城市大众运输（公共汽车，地铁和电车）以及其他城市运输方式是城市面临的主要挑战。在世界各地的几个人满为患的城市中，现有的城市流动系统根本不足。有害的排放，事故，棘手的拥塞和计划外的操作只是全世界造成交通混乱的关键问题之一。自主和无人驾驶的电子活动肯定会减轻这种干扰。这些新的城市电子活动模式将是明智的，没有人为错误。建立可持续和高效的自动驾驶基础设施的关键要素肯定包括电气化运输。机会性的静态充电和动态性，城市自动e-Mobility和Mass E-Transport的动态充电，由高能电池或高功率超级电容器提供动力，将是小时的需要。新型的电力电子转换系统和创新的线圈设计将在将高能/高功率电动存储系统与充电基础设施相连。 拟议的NSERC DG计划专门针对上述问题，重点介绍了通用，广泛的无线快速充电基础架构的设计。将设计，开发，测试和验证静态（机会充电）以及动力（动态充电）系统。无线功率传输（WPT）可以基本分为两种方法：电感功率传输（IPT）和电容式功率传输（CPT）。 IPT是一种更具成熟的方法，而CPT是一种新兴方法，目前仅适合低功率水平（高达1.0 kW）。拟议的NSERC DG计划将旨在应对推进两种WPT方法的最先进的几个关键挑战。该提案的具体重点是高功率，高效静态和运动型快速充电，用于未来的城市自动启动性模式以及从电子自行车到电子摩托车的大规模电动运输。 WPT充电器评级范围为1.0 kW至50.0 kW。总体程序分为6个主要任务：1）IPT Magnetics（COIL）设计； 2）新型WPT电源电子转换器设计； 3）高级WPT控制器开发； 4）设计（动态）机会快速充电器（50 kW）的设计； 5）CPT的电容设计；混合IPT/CPT设计； 6）EMI屏蔽。 上述独家研究目标使拟议的计划特别独特且专业化。就整体效率和自主性电子运输/电子传输基础架构的总体效率和绩效提高而言，这项研究绝对会导致未来的进步，更具体地说。
