PULSE CURRENT GENERATION METHOD Russian patent published in 2004 - IPC

FIELD: pulse engineering; high-pulse power engineering.

SUBSTANCE: proposed method includes build-up of magnetic field along axis of semiconductor tube accommodating winding coupled with load. Magnetic field is built up along tube while it is in normal (non-superconducting) state; tube is cooled down to temperature lower than that of superconductor junction, external magnetic field is reduced, then tube is changed-over to normal state. Device implementing this method has primary winding connected to power supply, secondary winding connected to load, and superconductor magnetic shield placed in-between, as well as control and cooling units. Magnetic energy is stored in space confined by superconductor tube; coupling constant between the latter and secondary winding may be close to unity; all these factors ensure efficiency of energy supply to load about 80 - 90% and reduction of device mass and size by 1.5 - 2 times.

EFFECT: enhanced effectiveness and energy supply efficiency, reduced size and mass of device.
