Equivalent circuit analysis model for influence of magnetic field coil on space field of bounded wave simulator

Abstract

The invention discloses an equivalent circuit analysis model for influence of a magnetic field coil on a space field of a bounded wave simulator. The equivalent circuit analysis model is mainly composed of a current source I, an equivalent capacitor C1 formed between an upper pole plate and a lower pole plate of the bounded wave simulator, an equivalent capacitor C2 formed at the part, corresponding to an external coil, of the upper pole plate of the bounded wave simulator, an equivalent capacitor C3 formed at the part, corresponding to the external coil, of the lower pole plate of the boundedwave simulator, a coil inductor L and a terminal matching load R of a bounded wave simulator loop. The equivalent circuit analysis model is simple and visual, the waveform characteristics of the space electric field can be effectively reflected, physical interpretation of electric field waveform distortion is given, the electric field waveform change rule after a coil type pulse magnetic field simulator and the bounded wave simulator are combined can be conveniently analyzed, and therefore the application range of an effect test is determined.

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...
