“…These benefits summarily include [16][17][18], [32] : 1 better correlation to free field irradiation in terms of surface and loom current distribution; 2 a more efficient transfer of energy into the rig resulting in lower power requirements; reduced radiation losses, giving a reduced radiation hazard and less RF pollution. However, the use of In validating the DCI technique [13][14][15][16][17][18], [28][29][30][31][32] , the most useful verification process is to make detailed comparisons with accepted test techniques [1][2][3][4][5][6][7][8][9][10][11] . The parameters such as airframe surface currents, wiring loom currents, power requirements, frequency [1][2][3][4][5], [13][14][15][16][17][18], [20][21][22], [32][33] have carried out a lot of research into this technology, including ineti (DERA, its predecessor organization) and BAe in UK, DSTO in Australia, EMCCons and EADS in Germany.…”

“…However, with the raising level of EM environment and EMC safety margin for aircraft systems, high test costs coupled with the complexity of new systems made HIRF and BCI method become less acceptable in their current forms. Even the original developers of BCI had made the point that the use of BCI on modern aircraft would become increasingly difficult [1][2][3][4][5], [21] . Consequently, direct current injection (DCI) technique was introduced [15] as an alternative procedure for conducting high level EM clearance test.…”

The direct current injection (DCI) technique is being widely researched for its application in aircraft EMC test as an alternative more efficient method for conducting system level EMC clearance test during high intensity radiated field (HIRF). This paper is focused on the research progress of DCI technique in aircraft EMC test, and gives discussion on DCI test configurations for aircraft systems. Moreover, the paper points out that most research on DCI has concentrated on investigating the frequency coverage of the technique, and the equivalence and validation of the technique as related to free field illumination. In the end, the paper outlines further work being actively undertaken in order to develop DCI technique in aircraft EMC test in the future. It is hoped that this paper will provide helpful guidance on the development of DCI technique in aircraft EMC test in China.

“…Essentially, the interference current is injected into the cable of the equipment to substitute for radiation susceptibility test [1,2]. As a kind of complementary method, the core of the BCI research is how to keep the equivalence with the radiation test method in broader application range and higher precision [3][4][5][6].…”

This paper presents a new kind of differential-mode current injection test method. The equal response voltage on the cable or the antenna port of the equipment under test (EUT) is regarded as equivalent principle for radiation and injection test. The injection and radiation response analysis model and the injection voltage source extrapolation model in high intensity radiated field are established. The conditions of using differential-mode current injection as a substitute for radiation are confirmed. On the basis of the theoretical analysis, the function and structure design scheme of the directional coupling device is proposed. The implementation techniques for the single differential-mode current injection method (SDMCI) and the double differential-mode current injection method (DDMCI) are discussed in detail. The typical nonlinear response interconnected systems are selected as the EUT. The test results verify the validity of the SDMCI and DDMCI test methods.

A representative bulk current injection transformer is characterized experimentally in both the time and frequency domains with the goal of quantitatively predicting its time domain response to the trapezoidal pulse specified in MIL-STD 461E.The time domain responses of the representative transformer, as computed from the experimentally obtained frequency domain transfer function and measured directly in the time domain, are in good agreement. We present for the first time a figure of merit, the time-domain pulse injection efficiency, which indicates the fraction of the available pulse energy from the generator that is inductively coupled to a particular structure such as a test fixture. This concept is generalized to the timegated pulse injection efficiency in order to account for a finite time window. It is seen that about 32.5 percent of the available energy in the trapezoidal pulse is delivered to the test fixture and that of this fraction most (30 percent of the total available energy) is delivered during a 30 nanosecond window, despite the overall extremely long time response of the probe. Finally, frequency domain power efficiency measurements are presented and compared with the time domain pulse injection efficiency.
