A Pspice Model of MOS-Controlled Thyrister for Circuit Simlulation

회로 시뮬레이션을 위한 MOS 제어 다이리스터의 PSPICE 모델

The advancement of power semiconductor devices has given great attribution to the performance and reliability or power conversion systems. But contemporary power devices have room for improvement. So much interest and endeavor are being applied to develop an improved power devices. The MOS-Controlled Thyristor(MCT)is a recently developed power device which combines four layers thyristor structure and MOS-gate. Owing to advantages compared to other devices in many respects, the MCT attracts much notice recently. Nowadays, in designing and manufacturing power conversion systems, the importance of circuit simulation for reducing cost and time is incensed. And to excute the simulation that resemble the real system as much as possible, to develop a model of power device that provides properly static and dynamic characteristics is important. So, this paper presents a PSPICE model of the MCT considering dynamic characteristics.
