摘要

The quality factor Q of coil used in wireless power transmission(WPT) is the crucial factor in the transmission distance and transmission stability.To reduce the resistance and increase the Q,the software of HFSS and VNWA frequency sweeper are use to analyze the circuit parameters under the condition of high frequency and the parallel multi-conductors structure of coils is designed,which will reduce the resistance and increase inductance to a stable range.Through the analysis,the structure satisfy the designing needs and can be used in the field of WPT.%用于无线电能传输(WPT)的线圈品质因数Q是决定传输距离与传输稳定性的关键因素.为减小线圈阻值并提高Q值,利用HFSS软件与VNWA逻辑分析仪,分析并验证线圈在高频情况下的电路参数,设计出多层导体并联的线圈结构,使线圈电阻减小,电感增大,进而使线圈Q值增大到一定范围内.经过分析,此结构达到了设计要求,可应用于WPT领域中.
