The fundamental structures and working principles of the new -t ype power device MCT (MOS-controlled Thyristor) were introduced, and the physic al state model in turn-off status modeled mathematically by the state-average method was discussed. The whole device was regarded as a system, whose stability was analyzed by the state-space analytical method. Thereby the maximum control lable turn-off current of MCT, and the relationship between the current and MCT 's structural parameters were deduced. The validity of conclusions drawn here w as proved using MATLAB/Simulink.
