| 英文摘要 | Background: efficient mid-range wireless power transfer between transmitter and the receiver has been achieved based on the magnetic resonant coupling method. the influence of electromagnetic field on the human body due to resonant wireless power transfer system (rwpt) should be taken into account during the design process of the system. objective: to analyze the transfer performance of the rwpt system and the change rules of the specific absorption rate (sar) in the human head model due to the rwpt system. methods: the circuit-field coupling method for a rwpt system with consideration of the displacement current was presented. the relationship between the spiral coil parameters and transfer performance was studied. the sar in the human head model was calculated under two different exposure conditions. results: a system with output power higher than 10 w at 0.2 m distance operating at a frequency of approximately 1 mhz was designed. the fem simulation results show the peak sar value is below the safety limit which appeared when the human head model is in front of the transmitter. conclusion: the simulation results agreed well with the experimental results, which verified the validity of the analysis and design. |
