Description

Technical Field

[0001] This utility model relates to an inductance detection component, specifically to an inductance pressure testing multi-point positioning device. Background Technology

[0002] Inductance testing equipment applies an AC signal of a specific frequency to the inductor under test and uses the detection of voltage, current, and phase difference to achieve accurate measurement of the inductance value. Based on the impedance characteristics of inductors: when an AC signal passes through an inductor, its impedance is proportional to the frequency. The inductance value can be derived by measuring the phase difference between voltage and current. It typically employs a high-precision signal source and high-speed sampling technology, combined with digital signal processing algorithms, to directly calculate the inductance parameters. When the inductor and a standard capacitor form a resonant circuit, the inductance value is determined by the frequency response. Its advantages include a high degree of automation, rapid completion of multi-parameter testing, and avoidance of human error; it supports a wide range of inductance values ​​and high-frequency scene testing, and also has non-contact measurement capabilities to avoid component damage.

[0003] In the existing technology: 202410446013.5 This invention relates to the field of electronic circuit technology and provides an inductance value testing circuit. The circuit includes a high-voltage DC power supply, a low-voltage DC power supply, a first switching transistor, a second switching transistor, an inductor, a current-limiting resistor, a current meter, a voltage meter, and a freewheeling diode. The positive terminal of the high-voltage DC power supply is connected to the current input terminal of the first switching transistor, and the negative terminal is grounded. The positive terminal of the low-voltage DC power supply is connected to the current input terminal of the second switching transistor, and the negative terminal is grounded. The current output terminals of the first and second switching transistors are connected to the first terminal of the inductor. The inductor, current-limiting resistor, and freewheeling diode are connected in series to form a first loop. After the first and second switches are turned off, the first loop is used for current freewheeling. The current meter is connected in series in the first loop to test the current of the inductor. The voltage meter is connected in parallel with the inductor to test the voltage of the inductor. This inductance value testing circuit can balance the defects of the pulse method and the DC method, effectively obtain the inductance value under different currents, overcome the inability or difficulty of the DC method to test the inductance value under high current, and avoid the excessive eddy current loss defect of the pulse method.

[0004] Although existing inductance testing components can balance the shortcomings of pulse and DC methods and effectively obtain inductance values ​​under different currents, overcoming the limitations of DC methods in testing inductance values ​​under high currents, they also have drawbacks such as not being able to test inductance at any time and not being efficient enough in inductance testing.
