容性负载和感性负载测量方法

Measurement methods of capacitive load and inductive load

探讨了容性负载和感性负载的6种不同的检测方法——示波器图像重合法、放电时间测量法、等效阻抗法、电桥法、LC振荡法,50Hz法,分析部分方法的优缺点,并通过简单的实验室仪器和Mulitisim仿真软件的验证,得出了相对准确、便捷地测出电容和电感的方法是50Hz法。对容性负载和感性负载测量方法的研究有着重要的意义,在电子领域里也有着十分广阔的应用前景。

This paper discusses six different methods of measurement emphatically, which include the oscilloscope image overlap method, the discharge time measuring method, the impedance method, the bridge method, the LC oscillation method and the 50 Hz method. The 50Hz method,which is the most accurate and convenient by comparison,is obtained by simple laboratory instruments and Mulitisim simulation software. At the same time, strengths and weaknesses of some methods are discussed. Research on capacitive load and inductive load has important value,and it has wide application potential in electronic field.
