Abstract

The invention relates to the field of circuit measurement, and more particularly relates to a power inductance measurement device. The power inductance measurement device comprises a power supply circuit, an inductance measurement circuit and a frequency test module. The power supply circuit is connected with the inductance measurement circuit and the frequency test module. The inductance measurement circuit is used for accessing power inductance for testing. The inductance measurement circuit is also connected with the frequency test module. Power inductance measurement is realized by designing the concrete circuit structure so that the power inductance measurement device is convenient to carry and low in cost in comparison with a measurement instrument LCR, and the power inductance measurement device has high test value accuracy and is simple in the whole assembling structure and low in weight in comparison with a handheld multimeter, and thus the burden and the workload of maintenance personnel can be reduced, the maintenance cost of the product can also be reduced and the operability of board card maintenance can be greatly facilitated.

Description

Technical field [0001] The invention relates to the field of circuit measurement, and more specifically, to a power supply inductance measurement device. Background technique [0002] In the actual application of splicing wall system equipment, it is sometimes necessary to confirm the working conditions of the various component parameters of the board power supply. The inductance of the power supply is regarded as the key component of the power supply. It is particularly important to measure the inductance parameters of the power supply. This small parameter determines The stability of the system is improved. [0003] In the prior art, in the specific application site of the splicing wall system equipment, when maintaining the power supply of the board and measuring the inductance and other parameters, the measuring instrument LCR is usually used for measurement. However, the measuring instrument LCR is bulky, heavy, and high cost. In order to reduce the cost of use and make it e...
