The Relationship of LRC Resonant Circuit Quality Factor and Inductance and Capacitance

在LRC串并联谐振电路中,回路的谐振特性通常由回路中的品质因数决定,而回路中的品质因数又与回路中的电容、电感、电阻有关。本文通过实验的方法,对回路的品质因数与电容和电感的关系进行了研究。得出了在串并联谐振电路中电容和电感的合理取值范围。所得结论将为今后LRC谐振回路的选择和设计提供一定的参考。

In LRC series-parallel resonant circuit,the resonant circuit is usually determined by the characteristics of the circuit quality factor,while the circuit quality factor and the circuit capacitance,inductance,resistance concerned.In this paper,the relationship between quality factor and capacitance and inductance is analyzed.The conclusions will be selected and designed LRC resonant circuit to provide a reference in the future.
