Optimization of The Control Circuit of A Wireless Power Supply System

Traditional wireless power transfer systems typically adopt the single-frequency control method to ensure a constant output voltage and current for different applications. This paper presents a different side of the control circuit of a wireless energy transfer system, i.e. input is made with two frequencies aiming to optimize the wireless energy transfer.The purpose of this paper is to show how it can be increased the efficiency of a wireless power system, in comparison with the traditional wireless power transfer systems with a single command frequency. An experimental prototype will be buit in order to verify the effectiveness of the proposed wireless energy transfer system and the control method.
