[0003] Spike voltage signal generators are key equipment for electromagnetic compatibility testing and are widely used in military, aerospace, and other fields. Currently, there are three main standards for spike voltage testing both domestically and internationally: GJB151, GJB181, and DO160. These standards have different requirements for parameters such as waveform characteristics, amplitude, duration, repetition frequency, and source impedance of spike voltage signals. For example, the GJB151 standard includes GJB151C 10µs and GJB151A 0.15µs. Currently, each standard corresponds to one spike voltage signal generator. If multiple standards are needed to test a product, three different spike voltage signal generators are required, which is not only resource-intensive and space-consuming but also leads to messy cable connections and affects experimental efficiency.

[0059] Specifically, the spike voltage signal generator has a frequency information access module on its panel. This module receives frequency information input by the user and sends it to the frequency signal control unit. The frequency signal control unit generates an initial frequency signal and sends it to the pulse switch control signal unit. The pulse switch control signal unit adjusts the initial frequency signal to obtain a frequency signal that meets the standard waveform requirements. The pulse switch control signal unit then inputs the frequency signal to the first and second optocouplers. The positive and negative input terminals of the first optocoupler are connected to the positive and negative terminals of the lithium battery power supply output from the first and second terminals of the first relay. The output of the first optocoupler is connected to the base of the first transistor, and the collector of the first transistor is connected to the positive terminal of the first power supply output from the first output terminal of the ninth relay. The emitter of the first transistor is connected to the negative input terminal of the first optocoupler. Therefore, when the output signal of the first optocoupler is at a high level, i.e., when the frequency control module outputs a switch-closing signal, the base voltage of the first transistor is higher than the emitter voltage, and the first transistor conducts.

At this time, the charging capacitor discharges, and the charging capacitor, coupling module, and first high-voltage switch form a circuit. When the output signal of the first optocoupler is at a low level, i.e., when the frequency control module does not output a switch-closing signal, the collector voltage of the first transistor is lower than the emitter voltage, the first transistor does not conduct, no circuit is formed, and the first capacitor charges.

The positive terminal of the first power supply output from the first output terminal of the ninth relay is connected to the negative terminal of the first power supply through the transformer in the coupling module and the conducting second transistor, thus forming a circuit. At this time, the charging capacitor discharges, and the charging capacitor, coupling module, and second high-voltage switch form a circuit. When the output signal of the second optocoupler is at a low level, that is, when the frequency control module does not output a switch closing signal, the collector voltage of the second transistor is lower than the emitter voltage, the second transistor does not conduct, no circuit is formed, and the capacitor charges.
