SUPERCONDUCTING D C SWITCH Russian patent published in 1994 - IPC

FIELD: electrical engineering cryoelectronics. SUBSTANCE: superconducting D. C. switch has key element composed of two isolated branches and controlling element. Controlling element is located on one of branches with section S₁. Section S₂ of second branch meets relation S₁≅ S₂≅ I_op/I_c, where I_op is total operational current fed to key element; j_c is critical density of current of superconducting material of key element. EFFECT: enhanced efficiency and reliability of switch. 1 dwg
