With an ongoing trend in mobile phone charger standardization, the next step to make the charging process even more user-friendly is to eliminate the physical cable connection between the charger and the mobile phone. To achieve a wireless charging of a mobile phone, a wireless power transfer system must be designed. One such system is presented in this paper. Theory of the wireless power transfer is explained and a functional wireless charger device is realized. Presented wireless charger device has the power transfer capability of around 0.5 W at a maximum distance of 2.5 cm, which is sufficient to charge a regular mobile phone.
