Introduction to Wireless Power Transfer
There have been dramatic progresses in wireless power transfer (WPT) in terms of power level (>50kW); efficiency (>90%), transfer distance (>300 mm) and misalignment tolerance (>300mm), thanks to optimized coil design, magnetic resonance tuning ability and soft switching of power converters employed in the WTP systems. This is the first course of five in a series developed on the topic of wireless power transfer by Prof. Chris Mi, fellow of IEEE and Professor of University of Michigan-Dearborn. In this first course, Dr. Chris Mi provides an overview of wireless power transfer technology and its application in electric vehicle charging. Different terminologies in wireless power transfer will be explained. Various methods for wireless power transfer will be discussed. Magnetic resonance and compensation methods will be introduced. Topics covered include: Conventional charging methods: conductive charging and battery swapping; ; Issues of conventional charging; History of WPT; Method of WPT: microwave, laser, ultrasound, magnetic resonance; Application of WPT; State of the art of WPT; Limitations of current WPT in EV applications; Resonant topologies of WPT: series-series; series-parallel, and parallel-series.
What you will learn:
- Compare wireless power transfer (WPT) with conventional charging methods
- Give examples of WPT application
- Summarize the advantages and limitations of WPT
- Explain four resonant topologies of WPT
