Our research team has been developed wireless power charging (WPC) system for electric vehicle using superconducting resonance coils in order to improve the transfer efficiency and stability. The strong eletromagnetic fields (EMFs) are generated around antenna (Tx) coil and receiver (Rx) coil in the high power applications of wireless power transfer (WPT) technology. As the Human Safety with respect to EMFs is an important measure, it is required to identify the condition under which human exposure complies with the safety regulations. Since the WPC system based on the resonance coupling method provides basic restrictions for EMFs in terms of internal electric field and specific absorption rate (SAR) to prevent effects on nervous system functions and excessive localized tissue heating, the effect of EMFs should be investigated. Especially, as the strong EMFs of high power applications such as electric vehicle (EV) and train charging system can affect the human body, various researches have been required in order to commercialize. In this paper, as a fundamental approach, authors indirectly investigated the influence of EMFs for food elements using fruits and vegetable since it is practically difficult to make clinical trial for human body. Thus, in this study, authors presented thermal distributions by EMFs between Tx and Rx coils under different frequency of 370 kHz and 750 kHz, respectively. As well as authors investigated rates of browning reactions in vegetable (potato) and fruits (banana, apple, pear), which are evaluated under exposure and non-exposure of EMFs with 370 kHz RF generator of 200 W.
