Modeling and designing wireless energy transfer circuit in high voltage based on magnetic coupling

A wireless energy transfer structure has been proposed in this paper. Wireless energy transfer based on coupled magnetic resonances is a technology which energy can be transferred via coupled magnetic resonances in the non-radiative near-field. Based on this structure, a simple model has been introduced, analyzed and simulated. Experimental results for verifying this model show that the model works well. The power that can be transmitted is up to 60Watt, the transfer efficiency is about 60 %, the distance of energy transfer is 11 meters, and the most important point; its frequency is 50 Hz. The prospective application of these circuits seems to be widespread in the fields such as mobile charging, industrial robot, aerospace, satellite simulators, wireless sensor networks, data transmission, subway stations and RFID technology.
