Embodiment 1

[0052] This embodiment provides a high-voltage square-wave pulse source for simulating a complex electromagnetic environment. The high-voltage square-wave pulse source includes: a DC high-voltage generator 1-1, a charging resistor 1-2, an energy storage cable 1-3, and a high-voltage switch K1 -4 and wireless remote control 1-5;

[0053] The charging resistor 1-2 adopts a non-inductive resistor of 80MΩ~120MΩ, which is connected in series in the circuit to act as a current limiting and voltage dividing function to protect the test equipment;

[0054] The energy storage cables 1-3 are coaxial radio frequency cables with strong anti-interference ability, good shielding performance, withstand voltage of at least 50000V, and impedance of 30Ω~70Ω;

[0055] The overall structure of the high-voltage switch K1-4 is divided into front-end compartment 3-1, main compartment 3-2 and rear-end compartment 3-3 from the incoming line end to the outgoing line end; Electromagnetic interference, ...

Embodiment 2

[0074] In this example,

[0075] 1) Charging resistor

[0076] The charging resistance adopts 80MΩ~120MΩ (recommended 100MΩ) non-inductive resistance, which is connected in series in the circuit, and acts as a current-limiting and voltage-dividing function to protect the test equipment. The inductance value of the charging resistor is very small and can be ignored to avoid parasitic oscillation and eliminate the influence on the high-voltage square wave pulse signal as much as possible.

[0077] 2) Energy storage cable

[0078] The pulse width of the high-voltage square wave pulse is determined by the length of the energy storage cable. The energy storage cable adopts a coaxial radio frequency cable with strong anti-interference ability, good shielding effect, withstand voltage of at least 50000V, and impedance of 30Ω~70Ω (50Ω recommended). The energy storage cable is composed of an outer insulating layer (2-1), an outer conductor (2-2), an insulating layer protection (2-3)...

Abstract

The invention belongs to the field of strong electromagnetic pulses and specifically relates to a high voltage square wave pulse source for simulating a complex electromagnetic environment. The high voltage square wave pulse source includes a DC high voltage generation device, a charging resistor, an energy storage cable, a high voltage switch K and a wireless remote controller. Compared with theprior art, by adopting the above technical scheme, high voltage square wave pulse signals having high voltage (100V-50,000V), short rising time (smaller than 1ns) and large bandwidth ( greater than 1000 MHz) and capable of being applied to element amplitude limiting response time and overshoot peak value voltage testing are simulated in a laboratory environment.

technical field [0001] The invention belongs to the field of strong electromagnetic pulses, in particular to a high-voltage square wave pulse source for simulating complex electromagnetic environments. Background technique [0002] The International Electrotechnical Commission (IEC) refers to an environment with an incident electric field strength >100V / M as a strong electromagnetic environment. Nuclear electromagnetic pulse (NEMP), lightning electromagnetic pulse (LEMP) and electrostatic discharge electromagnetic pulse (ESD EMP) are all strong electromagnetic pulses, which have a strong interference and destructive effect on electronic systems, and can make unprotected missiles or satellites The electronic equipment on board and the ground command and control system and other equipment are seriously interfered, destroying the program of the electronic computer, and even making it lose its normal working ability. Therefore, it is particularly important to study the inter...
