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 trans...

This work presents a novel highly efficient and low-stress battery charger with a resonant switch converter— based on resonance and zero-voltage-transition soft-switching theory—that reduces defects associated with high voltage and high current stresses caused by the resonance of traditional resonant circuits. The novel battery charger meets the requirement that all circuit components must oper...
