Pulse large current generator, pulse current generation device and preparation method thereof

The invention discloses a pulse large current generator, a pulse current generation device and a preparation method thereof. The pulse large current generator comprises a coil skeleton, a primary coiland an induction ring orderly nested from inside to outside, and a fixed ring sleeved out of the primary coil to parallel to the induction ring; an air gap is formed between the primary coil and theinduction ring; the input end of the primary coil is used as the input end of the pulse large current generator, the induction ring is an annular conductor structure, an insulation gap is arranged onthe induction ring, and two ends of the insulation gap are taken as the output end of the pulse large current generator; the fixed ring is used for commonly fixing the primary coil and the induction ring together with the coil skeleton; the pulse current enters the primary coil through the input end of the pulse large current generator, thereby realizing the aim of boosting the pulse current to the high pulse current throug
