恒流源充电二极管放电的互感值测量方法

介绍恒流源充电二极管放电的互感值的测量方法。其测量原理是采用开关电路，以恒流源电路向互感器的原边线圈充电，只经过二极管放电，定时测量稳定放电的时间和副边线圈的开路电压来测量互感值。分别论述了测量原理，并设计了试验和标定方法，通过试验和数据分析证明这种互感值测量位移的方法可行，不采用高频正弦激励，即可测量较小的互感值。

Mutual Inductance Measurement by Charging with the Constant Current Circuit and Discharging Through a Diode

The mutual inductance measurement is introduced by charging with the constant current circuit and discharging through a diode with switching two-winding transformer.The mutual inductance measurement principle is that using the switching circuit and the constant current circuit to charge the primary winding,and then only through a diode discharging,the mutual inductance is determined by measuring the stable discharge time and the open-circuit voltage of the secondary winding.The principle is discussed,and the test and calibration method are designed.Experiments and data analysis prove that the mutual inductance measurement is feasible,and it can measure a smaller mutual inductance without using a high frequency sinusoidal excitation.
