Fundamental Theories of Wireless Power Transfer Slides

Rapid expanding technologies of wireless power transfer (WPT) to mobile devices and electric vehicles (EVs) make electric charging more convenient, safe, and automatic. WPT business and industries are growing fast, and more people are getting involved in this area. Innovation on WPT is highly sought in this area, however, no substantial progress in technology is possible without thorough and philosophical understanding of WPT. It is very often ignored and underestimated by engineers and practitioners, but theory is the basis of great innovation. In this webinar, an overview of WPT and its fundamental principles are introduced first. Several theories on inductive power transfer (IPT), mostly invented by Prof. RIM, are explained, including the coupled coil models, gyrator circuit models, magnetic mirror models, active electromagnetic force (EMF) cancel models, and general unified dynamic phasor models. A few application examples of IPT for dynamic and static EV charging and mobile devices are shortly given. This webinar is based on two new books by Prof. RIM, Phasor Power Electronics, Springer, 2016, and Wireless Power Transfer for Electric Vehicles and Mobile Devices, Wiley, 2017.
