Problems solved by technology

But there are the following disadvantages: 1. The energy storage density of the capacitor is not high, it is difficult to reduce the volume of the pulse power supply; 2. And the capacitor cannot store energy for a long time, and the energy storage effect is not good

The problem with it is that if you want to get a very high amplitude pulse current, you need to superimpose a lot of superconducting energy storage inductors, which makes the system very large in scale

Its problems are: 1. Repeated use of superconducting energy storage inductance quenching will reduce the service life of superconducting energy storage inductance; The primary winding of the pulse transformer, which is not conducive to the improvement of the transformer coupling coefficient, will also reduce the output efficiency of the power supply; 3. To obtain a large pulse current output under the condition of a large transformer ratio, a very large quench resistance is required , which puts higher requirements on the material properties of superconductors and quench triggering technology;

There is also a prominent problem in this mode that when the superconducting energy storage inductor discharges the pulse transformer, it will generate a high pulse voltage, which has very high requirements for the disconnect switch, and the output efficiency of this circuit mode is low.
