| 中文摘要: |
| 本文以归一化频率 为变量,推导了RL-C谐振电路阻抗的模|Z|与Q及 的关系表达式,并推导给出了阻抗的最大值发生时的归一化频率 与Q的关系式。通过举例进一步分析了谐振点处阻抗与阻抗的最大值发生的频率及相对误差随Q的变化而变化的规律。 |
| 英文摘要: |
| Taking normalized frequency as a variable, this paper derives the expression of the relationship between the mode |Z| and Q of RL-C resonant circuit, and derives the relationship between normalized frequency * and Q when the maximum impedance occurs. The frequency and relative error of the maximum impedance and impedance at the resonance point are further analyzed with an example. |
