本文提出了一种计算单层空心螺线管电感自电容的方法。在单层空心电感中，自电容是由于导体匝间电容引起的。建立了确定均匀和非均匀分离导体匝的单层空心电感匝间电容的分析框架。考虑了导线绝缘涂层的影响。给出了一个典型的单层空心电感的设计实例，并对其自电容和自谐振频率进行了预测。所提出的分析方法进行了测试的实验测量所设计的电感器。推导出的解析表达式是有用的设计高频（HF）和甚高频应用，如电磁干扰/电磁兼容滤波器和无线电和电视发射机的空心电感器。
This letter presents the technique for estimating the self-capacitance of single-layer air-core solenoid inductors with separation between the insulated turns. In single-layer air-core inductors, the self-capacitance is due to the conductor turn-to-turn capacitances. The analytical framework to determine the turn-toturn capacitances of single-layer air-core inductors with uniformly and nonuniformly separated conductor turns is established. The influence of the wire insulation coating is taken into consideration. A representative design example of a single-layer air-core inductor is presented and its self-capacitance and self-resonant frequency are predicted. The presented analytical approach was tested by experimental measurements on the designed inductor. The derived analytical expressions are useful for designing air-core inductors for high frequency (HF) and very HF applications such as electromagnetic interference/electromagnetic compatibility filters and radio and TV transmitters.
