Investigation of magnetic properties for different coil sizes of dynamic wireless charging pads for electric vehicles (EV)

: Electric vehicles (EV) have been introduced in the recent years due to public awareness of the effect of gas emission from traditional cars and the extinction of petroleum natural resources. For charging EV, dynamic wireless charging is considered in this paper. This is because it is more conve...
