Metal - high current control circuit and the system comprising the high-current control circuit with an insulator transition device

摘要

Provided are a high current control circuit including a metal-insulator transition (MIT) device, and a system including the high current control circuit so that a high current can be controlled and switched by the small-size high current control circuit, and a heat generation problem can be solved. The high current control circuit includes the MIT device connected to a current driving device and undergoing an abrupt MIT at a predetermined transition voltage; and a switching control transistor connected between the current driving device and the MIT device and controlling on-off switching of the MIT device. By including the metal-insulator transition (MIT) device, the high current control circuit switches a high current that is input to or output from the current driving device. Also, the MIT device constitutes a MIT-TR composite device with a heat-preventing transistor which prevents heat generation and is connected to the MIT device.
