Abstract

A wireless inductive charging system having a DC power source (10) and a DC/AC inverter (12) being fed by the DC power source (10) and generating an AC charging signal. A primary coil (Lp) is fed by the AC charging signal and transmits a wireless charging signal to a secondary coil (Ls) of a device to be charged (20). A space harmonic elimination stage (19) is provided which is configured to eliminate harmonics from the AC charging signal generated by the DC/AC inverter (12) before feeding the primary coil (Lp). The DC/AC inverter (12) and the space harmonic elimination stage (19) are located within an EM shielded structure (11).
