Abstract

The invention discloses an equivalent circuit analysis model for the influence of a magnetic field coil on the space field of a bounded wave simulator. The equivalent capacitance C2 formed by the part corresponding to the upper plate of the device and the magnetic field coil, the equivalent capacitance C3 formed by the part corresponding to the lower plate of the bounded wave simulator and the magnetic field coil, the coil inductance L and the circuit of the bounded wave simulator The terminal matches the load R. The equivalent circuit analysis model provided by the present invention is simple and intuitive, can effectively reflect the waveform characteristics of the space electric field, and provides a physical explanation for the distortion of the electric field waveform, and can conveniently analyze the combination of the coil pulse magnetic field simulator and the bounded wave simulator The change rule of the electric field waveform can determine the scope of application of the effect test.

Description

technical field [0001] The invention relates to the field of electromagnetic field environment simulation and testing, in particular to an equivalent circuit analysis model for the influence of a magnetic field coil on the space field of a bounded wave simulator. Background technique [0002] Bounded wave simulator, also known as guided wave simulator, is a typical device widely used in high-power electromagnetic environment effect tests such as nuclear explosion electromagnetic pulse and lightning electromagnetic pulse. The interior of the parallel section of the simulator can be approximated as a vertically polarized plane wave, and the field intensity distribution is uniform, which is an ideal pulse electric field test area. Using a high-voltage high-energy pulse source to discharge a single-turn or multi-turn coil is currently the most common pulsed magnetic field generator. The device is simple to construct, and the magnetic field can be flexibly adjusted. The inside o...
