Dynamic Wireless Charging of Electric Vehicles

This chapter reviews the concept of dynamic wireless power transfer and its advantages compared to the static power transfer. Dynamic wireless charging of moving vehicles is becoming an attractive option for future public and private transportation systems. On-road dynamic charging of electric vehicles by wireless power transfer (WPT) systems has emerged recently as a clean and convenient means for future public and private transportation. The idea of electrical power transfer without mechanical contact, so-called wireless power transfer, was a human dream at the early stages of the electrical power conversion where Nikola Tesla took the preliminary steps in the late nineteenth and early twentieth centuries. Electromagnetic radiation-based power transfer in short distances can be used to lighten fluorescent lamps with several watts, for instance. The resonance frequency of the primary and secondary sides is often considered identical.
