Wireless power transfer (WPT) technology has been developed and encountered in a wide range of charging applications. This paper describes the WPT model with an experimental validation to obtain the relation between the inductive coupling parameter and electrical characteristic. The important aspect in the WPT design with inductive coupling method is the range between coupling device, transmission signal frequency and inductance. Selected wire diameter, coil diameter and the ratio of coil turn number are chosen according to the inductive coupling observation based on electromagnetic field. Measured voltage, current and power were also investigated. The mechanism of energy transfer is conducted by exploration of electrical characteristic between transmitter and receiver, respectively. The measured electrical parameter can be directly influenced by these indicators associated with the efficiency investigation. The highest efficiency was achieved by 40 J.1H inductance of 35.85%. The higher efficiency of the transferred energy was obtained by the inductor with a low inductance value. © 2018 IEEE.
