AC impedance test method, computer readable storage medium and electronic equipment

Abstract

The embodiment of the invention provides an alternating current impedance test method, a computer readable storage medium and electronic equipment, and the method comprises the steps: receiving a user instruction, and analyzing a frequency value in the user instruction; determining a size relationship between the analyzed frequency value and a preset threshold value; when the frequency value is smaller than a preset threshold value, the feedback electronic load is controlled to apply a sine test signal with the analyzed frequency value to the tested equipment; when the frequency value is greater than a preset threshold value, controlling a feedback electronic load to apply a basic test signal to the tested equipment, and controlling a disturbance load to apply a disturbance test signal of which the frequency is the analyzed frequency value to the tested equipment; thus, electric energy generated in the alternating current impedance test process is fed back to the power grid, and electric energy waste is avoided as much as possible; the heat dissipation pressure is reduced, and the size of the test equipment is reduced; the service life of the disturbance load is prolonged, and the damage risk of the disturbance load is reduced.

Description

technical field [0001] The present invention relates to the technical field of power electronic equipment testing, and in particular, to an AC impedance testing method, a computer-readable storage medium and electronic equipment. Background technique [0002] AC impedance test, also known as Electrochemical Impedance Spectroscopy (EIS) test, is an electrochemical measurement method using a small amplitude sine wave current or voltage signal as the excitation source. When sine wave disturbance signals of different frequencies act on the electrode system, the electrode system will generate a corresponding current or voltage response signal. From these signals, the impedance or admittance of the electrode can be obtained, that is, the internal resistance of the device under test can be obtained. AC impedance testing can reflect the internal state of the device under test, thereby helping to diagnose equipment failures and improve equipment performance. [0003] The low-power A...

However, in this test method, the high-power electric energy generated during the test is often consumed in the form of heat, and the energy is wasted; at the same time, in order to dissipate heat, more cooling fans need to be installed around the DC electronic load, resulting in a bulky device, and The noise is also very loud; if the heat dissipation is unreasonable, it will seriously affect the normal operation of other equipment, and its own devices are also easily damaged due to high temperature

AC Impedance Analyzer is used all the time, its life is shortened and the probability of damage increases
