Abstract

The invention relates to the technical field of inductors, and particularly relates to a high-precision switching type inductance tester comprising a master controller circuit, a constant current source circuit, a switching circuit and a detection circuit. The switching circuit is connected with the output end of the constant current source power supply end. The output end of the switching circuit is connected with the inductor. The master controller circuit is connected with the control end of the switching circuit to control on / off of the switching circuit through the master controller circuit so that the constant current source circuit is enabled to perform charging and discharging of the inductor. The input end of the detection circuit is connected with the switching circuit, and the output end is connected with the master controller circuit and used for transmitting the measurement data of discharging of the inductor to the master controller circuit. The master controller circuit receives the measurement data transmitted by the detection circuit and performs analysis and calculation so as to obtain the induction value of the inductor. The inductance tester is simple in design, small in size, convenient to operate, low in cost, fast in speed and quite high in anti-interference capability.

Description

technical field [0001] The invention relates to the technical field of inductance meters, in particular to a high-precision switch-type inductance tester. Background technique [0002] Inductors are components that can convert electrical energy into magnetic energy and store them, also known as chokes, reactors, and dynamic reactors. The role of an inductor is to resist changes in current, if there is no current flowing through the inductor, it prevents current from flowing through it; if there is current flowing through it, it will try to maintain the same current when the circuit is open. It has the characteristics of preventing the passage of alternating current and allowing direct current to pass through smoothly. The higher the frequency, the greater the coil impedance. Therefore, the main function of the inductor is to isolate and filter the AC signal or form a resonant circuit with capacitors, resistors, etc. Inductors are widely used in electronic circuits. As one ...
