因为GTO的导通原理和普通晶闸管类似,因此分析GTO的工作原理主要就是分析其关断机理.从上述分析可以看出,理解GTO的关断机理主要可从两方面考虑:一是和普通晶闸管相比,GTO的α1/α2比较大,N1P2N2晶体管控制灵敏,而α1+α2较小,接近于1,使GTO导通时接近临界饱和;二是GTO的多元集成结构使每个GTO元阴极面积很小,门极和阴极间的距离大为缩短,P2基区横向电阻很小,使得可以用门极负电流关断GTO.

Because GTO leads passes the principle and the ordinary crystalthyratron similar,therefore analyzes GTO the principle of work mainlyis analyzes it to shut off the mechanism.May see from the aboveanalysis,understood GTO shuts off the mechanism mainly to be possibleto consider from two aspects:One is and the ordinary crystalthyratron compares,GTO alpha 1/ alpha 2 quite big,N1P2N2 transistorcontrol keen,but alpha 1+ alpha 2 smaller,approaches to 1,causesGTO to lead passes time approaches critically is saturated; Two is theGTO many Yuan integrated structure causes each GTO Yuan negative polearea very slightly,the gate distance with the negative pole betweengreatly in order to reduce,the P2 base area transverse resistancevery is extremely small,causes to be allowed to use the gateextremely negative current to shut off GTO.
