The pulse capacitor 33 adopts a superconducting magnetic energy storage technology, has low storage loss and can store energy for a long time, which has unique advantages for pulse power systems which need to accumulate energy for a long time and store energy for a long time, such as space electromagnetic emission power supply systems, and more importantly, the superconducting magnetic energy storage system (SMES) is easy to control and can control pulse discharge waveforms; and the power-on density of the superconducting wire is far greater than that of a normal conducting conductor such as copper, and the volume and the weight of the energy storage device made of the superconducting wire are far smaller than those of the conventional energy storage device, so that the light weight and the miniaturization of a power supply can be realized.

The control circuit device 34 is composed of a high-speed controllable switch, an IGBT, a micro switch and a large-current diode, and obtains current outputs suitable for different loads by controlling the charging/freewheeling/discharging states of each energy storage module.

The micro switch in the circuit controller can trigger the photoelectric switch 4 to discharge at the next stage only when the armature 9 passes through, so that the phenomenon that the object enters the transmitting barrel to shield the photoelectric switch 4 to cause false triggering is avoided.

The primary side of the transformer 32 is formed by winding a plurality of turns of superconducting tapes in parallel, the negative side of the transformer 32 is formed by connecting a plurality of groups of superconducting tapes in parallel, and the transformation ratio K value is generally 5-50, so that stable and instant boosting is ensured.
