Problems solved by technology

[0004] However, in the above method, the tested devices are all low AC voltage power supply equipment, and for high AC voltage (such as 10kv AC voltage) power supply equipment, the surge signal generator is directly connected in series to the power supply of the high AC voltage power supply equipment. loop, may cause the surge signal generator to malfunction
In this way, it may not be possible to complete the test process of the above-mentioned equipment under test's tolerance to surge signals

Abstract

The embodiment of the invention provides a surge immunity test system, method and device, relates to the technical field of electromagnetic compatibility, and can smoothly complete a testing process of a tolerance degree of power supply equipment (namely tested equipment) with a high alternating-current voltage to surge signals and improve the practicability of surge immunity testing. The method comprises the steps that a voltage dividing device collects a first power parameter of a target loop, wherein the first power parameter includes a voltage amplitude of the target loop and a voltage phase angle of the target loop; the voltage dividing device determines a second power parameter according to the first power parameter, and the second power parameter includes a target voltage amplitudeand a voltage phase angle of the target loop; and under the condition that the voltage dividing device determines that the target voltage amplitude is smaller than or equal to a voltage amplitude threshold value, the voltage dividing device sends the second power parameter to a surge signal generator.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electromagnetic compatibility, and in particular to a surge immunity test system, method and device. Background technique [0002] Currently, by applying a surge signal to a device under test (such as a television), the tolerance of the device under test to the surge signal can be determined. [0003] Specifically, the surge signal generator can periodically generate surge signals of different sizes (specifically, different voltage amplitudes), and then the surge signal generator can send the surge signals of different sizes to the device under test respectively. Furthermore, after the device under test receives the surge signals of different sizes, the surge signal that the device under test can withstand can be determined according to the working state of the device under test. If the device under test can work normally after receiving a certain surge signal, it is determined that...
