Research on Theoretical Model of Injection Equivalently Replacing Radiation Based on Network Link for Two-Wire Interconnection System
It is very difficult to simulate the radiation effect of high field electromagnetic environment in a large-scale space
and the existing bulk current injection technology has limitations in the application of nonlinear systems. The research on the equivalent alternative radiation test method of bulk current injection for nonlinear systems in the parallel-double-wire coupling channel is carried out. The response analysis and calculation models of the device under test under radiation and injection conditions are established respectively. Taking the equal response of the device under test as the equivalent basis
it is deduced that the equivalent corresponding relationship between the radiated field intensity and the injected excitation voltage source is linear
and it is verified by the electromagnetic simulation software CST. The test method of bulk current injection equivalent to replace radiation is proposed
and it has passed the verification of the actual installation test. The research results show that the proposed method of bulk current injection can be accurately equivalent to the radiation test of the nonlinear system in the parallel-double-wire coupling channel
