technical field [0001] The invention relates to a capacitor, in particular to a high-voltage megavolt combined low-inductance medium storage capacitor. Background technique [0002] An electromagnetic pulse simulator is a device that generates fast leading edge electromagnetic pulses. Its composition diagram is as follows figure 1 shown. Generally, a two-stage compression circuit is often used to realize it, that is, a two-stage pulse compression through a Marx circuit, a middle storage circuit and a 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 typical working process of the simulator is: the primary pulse generator 1 generates a high-voltage pulse with a slow leading edge, and quickly charges the middle storage capacitor 3 through the high-voltage pulse output terminal 2. After the middle storage capa...
