According to Yonhap News Agency on October 27, researchers from the South Korean National Science and Technology Research Association (NST) said on October 27 that they have developed 1400 volt and 2500 volt silicon MCT semiconductor technology for high-voltage switching in the field of pulse power supply.

Pulse power supply is a technology that uses low power to store electricity and then releases electricity with high power in a very short time. The device that controls the pulse power supply current is a high-voltage switch. As a type of power semiconductor component, MCT power semiconductor is the core component of high-voltage switches, but previously, products above 1400 V level and above were not yet produced independently in South Korea. The research team developed 1400 V-class and 2500 V-class MCT power semiconductors, which achieved the first domestic production in Korea. The research team claimed that the MCT power semiconductors they developed can withstand high voltages of up to 1,600 volts and above 3,000 volts, respectively. The head of the research team of

claimed: "This achievement can not only be used in cutting-edge fields, but also in the development of various power components in the field of civil needs."
