description The invention belongs to the technical field of electronic circuits, and provides an inductance value test circuit which comprises a high-voltage direct-current power supply, a low-voltage direct-current power supply, a first switch tube, a second switch tube, an inductor, a current-limiting resistor, a current tester, a voltage tester and a freewheel diode. The positive electrode of the high-voltage direct-current power supply is connected with the current input end of the first switching tube; the positive electrode of the low-voltage direct-current power supply is connected with the current input end of the second switching tube; the current output end of the first switching tube and the current output end of the second switching tube are connected with the first end of the inductor; the inductor, the current-limiting resistor and the freewheeling diode are connected in series to form a first loop, after the first switch and the second switch are disconnected, the first loop is used for current freewheelin
