中文摘要:
      本文在介绍用 PLL(Phase-Locked Loop锁相环)电路进行频率跟踪的原理和实质的基础上,给出一种能够跟踪压电换能器并联谐振频率fp区间的具体电路,并通过实验研究了匹配电感和负载等对电路跟踪性能的影响.结果表明,这个电路具有很好的频率跟踪和功率自动调节性能.
英文摘要:
      Based on a discussion on the principle and essentiality of piezoelectric transducer’s frequency tracking by the PLL circuit, a practical circuit for tracking the fp region is given. The effect of matching inductor and load on the circuit’s tracking ca- pability was studied through experiment. The result shows that this circuit has a good performance in both frequency tracking and automatic power adjusting.
