Wireless power transfer (WPT) today is not just limited to low power applications like smartphones or biomedical devices but has reached power levels up to 22 kW [1]. Wireless charging of electric vehicles is one of the widely researched area in the field of WPT. This paper deals with the dimensioning and comparison of inductive coils for 11 kW power transfer taking factors such as unidentical stationary and mobile coil sizes, different DC link voltages on stationary and mobile side, coupling factor and magnetic flux density into consideration.
