Abstract: The wireless power transmission technology of self-resonance coupling coils is a new type technology different from the wireless power transmission technology of induction coupling coils. The technology could realize power transmission of medium distance between power supply equipment and power use equipment. Introduction was made to the working principle of wireless power transmission technology of self-resonance coupling coils. This paper carried out classification study on factors which had impacts on the wireless power transmission efficiency of self-resonance coupling coils and gave the method to lift system transmission efficiency. It is pointed out that in actual application, to realize max efficiency of the system is to determine the proper circuit working method, resonance frequency and coils parameters.
Key words: wireless power transmission; resonance coupling; transmission efficiency; medium distance
