Abstract

The invention discloses a pulse current injection source for an HEMP conduction immunity test, and relates to a pulse current generating apparatus technology. The injection source comprises a high-voltage charging power source, a Marx generator, an impedance match module and a controller, wherein the output end of the high-voltage charging power source is connected with the input end of the Marx generator, the high-voltage charging power source is used for providing high-voltage charging power supply for the Marx generator, the output end of the Marx generator is connected with the input end of the impedance match module, and the Marx generator outputs dual-index waves and outputs dual-index pulse current waveforms conforming to requirements of standards after shaping and impedance matching of the impedance match module. The pulse current injection source can conveniently change the output current waveforms, peak currents and source internal resistance of the pulse current injection source, facilitates realization of high-altitude nuclear power magnetic pulse conduction immunity tests with different standards by use of one pulse current injection source, and is high in versatility and convenient to use.

Description

technical field [0001] The invention relates to the technique of a pulse current generating device, in particular to a pulse current injection source used for HEMP conduction immunity test. Background technique [0002] High-altitude nuclear electromagnetic pulse (High-altitude nuclear EMP, HEMP) can generate conduction current on power lines, data transmission lines or casings through conduction coupling, interfering with the normal operation of electronic equipment. In order to assess the high-altitude nuclear electromagnetic pulse conduction immunity of electronic equipment, the IEC International Electrotechnical Commission IEC61000-4-25 stipulates the high-altitude nuclear electromagnetic pulse conduction immunity test level and test method. The US military standard MIL-STD-188-125 stipulates the high-altitude nuclear electromagnetic pulse conduction test requirements and pulse current injection test methods. [0003] However, the injection current waveform and the inte...
