摘要
介绍一种向被测电感充放电来测量电感值的方法。其原理是用开关电路控制电感充放电,通过示波器观察电感的电压电流波形,分析电感的特性。按该原理设计了试验电路,并用来测量工字形电感,测量范围为20~1000μH,偏差小于10%。
The method of measuring inductance by charging or discharging the inductor is described. Its princi- cording to the principle, a test circuit is designed to measure the I-shaped core inductor, the measuring range is 20 - 1000μH, and deviation is less than 10%.
