摘要
报道了一种消化道微创诊疗微系统的无线体外供能装置,它主要由利用锁相环的自动频率跟踪电路和采用移相的调功电路构成。实验表明,该供能装置能自动频率跟踪和调节输出功率,使接收能量稳定。
A wireless energy transmission system for the MEMS system inside alimentary tracts is reported here in the paper. It consists of an automatic frequency tracking circuit of phase lock loop and phase shift PWM control circuit. Experimental results show that the energy transmission system is capable of automatic frequency-tracking and transmission power-adjusting and has stable received energy.
