METAL-INSULATOR TRANSITION TRANSISTOR SYSTEM INCLUDING CRITICAL CURRENT SUPPLY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a circuit necessary for producing a metal-insulator transition (MIT) phenomenon that exceeds a limit of an electronic element that generates a large amount of heat although it is not possible to make a large current flow.SOLUTION: In a system including an MIT transistor (MITR1) 10 of an MIT critical current supply element to drive an MIT transistor (MITR2) 11 and adopting a switching power supply as current supply equipment, a switching power supply 31 includes the MIT transistor 10 and a switching transformer 6. The MIT transistor 10 functions as a switching TR. An AC current generated on the secondary coil side of the transformer 6 is applied to a control terminal C of the MIT transistor 11.
