As the mobile devices develop, the contact type wireless power transmission technologies face its limitation, and there are demands for convenient charging systems. Under the demands, non-contacting wireless power transmission system has been studied using magnetic resonance. Magnetic resonance type system uses four coils to transmit electrical power further. However, the 4-coil system has disadvantages in its size of transmission/receiving coils and difficulties in impedance matching. To improve the 4-coil system, 2-coil wireless power transmission system with transformers is proposed and analyzed. The existence of the transformers at the transmission part and the receiving part make the impedance matching between the system and the load comfortably and make the 2-coil system transmit power further. Circuit simulation is used to analyze the power transmission coefficient of the proposed 2-coil system with the 4-coil system. It can be seen through the simulation that the 2-coil wireless power transmission system with the transformers has analogous power transmission coefficient to that of the 4-coil wireless power transmission system. As a result, the wireless power transmission system can be made into a smaller size by using transformers in the 2-coil wireless power transmission system.
