Problems solved by technology

Since the magnetic permeability of air is 1, the air-core coil will not be able to complete the high-current output coupling
The coupler needs to use a magnetic core to improve the coupling efficiency, and the increase of the magnetic core will increase the leakage inductance of the coupler, and the rising edge of the output pulse current waveform will slow down. Excessive leakage inductance will make the pulse current waveform not meet the standard Require
Therefore, the difficulty of coupler design lies in the coupling efficiency and the balance adjustment of the rising edge of the waveform.

Abstract

The invention discloses an inductive coupler for the indirect injection of an HEMP short pulse current source. The inductive coupler comprises an input module, a coupling module and an output module. Through the matching design of the input end structure of the input module and the magnetic ring of the coupling part, the separable connection of the HEMP short pulse current source and the coupler is realized, the pulse current is indirectly injected into the tested equipment in the working and non-working states under the condition of meeting the insulation and voltage resistance requirements, the normal working state of the pulse source circuit is not changed after the coupler is connected to the pulse source, and it is guaranteed that when the pulse current of the HEMP short pulse current source is indirectly injected through the coupler, the output pulse current can meet the requirement of a pulse current injection test.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to an inductive coupler used for indirect injection of HEMP short pulse current sources. Background technique [0002] With the development of electromagnetic compatibility technology and the increasingly complex electromagnetic environment, electronic equipment needs to have a certain electromagnetic protection capability to meet the requirements of people's life and work, so as to ensure that it can still work normally when it is subjected to a certain degree of electromagnetic interference. [0003] In order to check the electromagnetic compatibility of electronic equipment, it is usually necessary to conduct related anti-interference tests, including pulse current injection tests. The pulse current injection test is to inject pulse current into the electronic equipment under test in a certain way, to simulate the working condition of the equipment when it is subjected to electromagne...
