Wireless power transmission (WPT) is an emerging area of power electronics that seeks to process and transmit electrical energy from a power source to an electrical load, such as the charging of cell phones, tablets, wearable devices, implantable medical devices, electric vehicles and aerial autonomous vehicles, without the use of connecting cables. WPT can be achieved through inductive coupling or capacitive coupling between the transmitter side and receiver side. The small and simple structure at the receiver end, make wireless transmission by capacitive coupling more attractive for power delivery in moving systems, such as drones. However, there are technical challenges that need to be overcome in order to achieve greater flexibility, versatility, and range of applicability. For example, there is a need to develop technical solutions to address the challenge of misalignment between the capacitive coupling resonators for moving systems applications. This proposal will develop innovative solutions in switching networks, converter structures, power control strategies, and sensing and control schemes that will address the technical challenges and lead to improved performance in transmission efficiency and versatility. Technically, the proposed research is timely and important. First, it is at the leading edge of research in the area of resonant capacitive coupling WPT technology and it addresses important issues that currently limit the application of the technology. Second, it provides the possibility of developing innovative solutions that will make significant contributions in advancing research in the area. Third, it supports the training of highly qualified personnel and the development of the next generation of innovators and leaders in this sector. Fourth, the research will provide opportunities to establish stronger relationship with Solace Power Inc., a local Rs talent, maintaining Canada’s leadership in knowledge in emerging technology, growing innovative firms and improving access to global markets.

无线电力传输（WPT）是电力电子领域的一个新兴领域，旨在处理和传输电能从电源到电力负载，例如手机、平板电脑、可穿戴设备、植入式医疗设备、电动汽车和空中自动驾驶汽车的充电，而无需使用连接电缆。WPT可以通过发送端和接收端之间的电感耦合或电容耦合来实现。接收端结构小而简单，使得电容耦合无线传输对无人机等移动系统的电力输送更具吸引力。然而，为了实现更大的灵活性、多功能性和适用范围，还需要克服一些技术挑战。例如，有必要开发技术解决方案，以解决移动系统应用中电容耦合谐振器之间不对准的挑战。该提案将开发交换网络、转换器结构、功率控制策略以及传感和控制方案方面的创新解决方案，以解决技术挑战，并提高传输效率和多功能性的性能。从技术上讲，本文的研究是及时而重要的。首先，它处于谐振电容耦合WPT技术领域的研究前沿，解决了目前限制该技术应用的重要问题。其次，它提供了开发创新解决方案的可能性，这些解决方案将对推进该领域的研究做出重大贡献。第三，它支持高素质人才的培训，以及该领域下一代创新者和领导者的发展。第四，该研究将提供机会与当地的r人才Solace Power Inc.建立更牢固的关系，保持加拿大在新兴技术知识方面的领导地位，发展创新型公司并改善进入全球市场的机会。
