Background technique [0002] The electromagnetic pulse simulator is a device that generates a faster leading edge, a narrower width, and a wider frequency band double exponential pulse. High-voltage electromagnetic pulse simulators are often realized by two-stage compression circuits, that is, two-stage pulse compression by Marx circuit, middle storage circuit and peaking circuit. The Marx circuit generates pulses of hundreds of nanoseconds, the storage circuit generates pulses of tens of nanoseconds, and the peaking circuit generates pulses of several nanoseconds. [0003] The peaking capacitor is the core component of the pulse power drive source. In order to obtain the fast leading edge of the pulse, the inductance of the peaking output loop must be reduced. That is to reduce the inductance of the peaking capac...
