本文针对轮胎内传感器的无线供电问题，重点设计了接收端模块中储能稳压电路。基于电磁共振发射原理，接收端接收到电信号经整流稳压后，为超级电容储能单元充电，此时超级电容停止放电；当无线电能接收中断时，则改由超级电容存储电能向后续电路输入。实验结果表明：当充电电流最大不超过1A时，由0．4V充到额定电压2．7V，并稳压在5V左右，使后续电路能正常工作，满足本系统对充电时间以及储能稳压输出的需求。

Aiming at the problem of wireless power supply for sensors build in the tire, an energy storage regulator of the receiver module is designed. On the basis of magnetic resonance principle, receiver module charges the super capacitor storage unit with electrical signal transmitted from the transmitter module and rectified and stabilized by the receiver module, super capacitor stops discharging at the moment. When the wireless power supply stops working, super capacitor storage unit can convey energy to the back-end circuit. Experimental result shows it can meet the system demand for charging time and regulated output that the super capacitor voltage can be charged from 0.4V to 2.7V, and stabilized around 5V with the charging current less than 1A.
