摘要
对Q值的定义方法、理论计算公式进行了综合剖析,首先辨析了品质因数的基本概念,然后从Q值的定义出发分别推导出串联谐振电路Q值的不同理论计算公式,并由实例证明推导出的计算公式在串联谐振电路中的正确性,还用仿真分析进一步验证了理论计算值,实例证明仿真的结果和理论分析值相吻合.
In this paper,comprehensive analyze the defined methods and theoretical formula of Quality Factor.First,analyze the basic concepts of the quality factor.Then,basic on the definitions of Quality Factor,deduce the theoretical formula of Quality Factor of the series resonant circuit in different way,and give examples to prove the correctness of these formulas applied in the series resonant circuit.Besides,use simulation to further verify the theoretical calculations.Example shows the simulation results and theoretical analysis of the value are consistent.
