新型功率器件MCT關斷模型的研究

摘要：本文介紹了新型功率器件MCT（MOS控制晶閘管）的基本結構、工作原理。詳細的探討了MCT在關斷情況下的建模，采用狀態空間分析法推倒出MCT的可關斷的最大電流與其結構的關系，并利用MATLAB/Simulink仿真證明結論的正確性。 敘詞：MCT 狀態空間分析法 可關斷最大電流 Abstract：The paper introduce structure and principle of the new MCT(Mos controlled thyristor)power device. Study on the turn-off modeling. Conclude relation of MCT’s maximum controllable current with MCT’s structure by the state-space analytical method. Simulation prove the conclude right by the MALAB/Simulink. Keyword：MCT State-space analytical method Maximum controllable current
