可控硅模块从X芯片上看,可以分为可控模块和整流模块两大类;
从具体的用途上区分,可以分为:普通晶闸管模块(MTC\MTX)、普通整流管模块(MDC)、普通晶闸管、整流管混合模块(MFC)、快速晶闸管、整流管及混合模块(MKC\MZC)、非绝缘型晶闸管、整流管及混合模块(也就是通常所说的电焊机专用模块MTG\MDG)、三相整流桥输出可控硅模块(MDS)、单相(三相)整流桥模块(MDQ)、单相半控桥(三相全控桥)模块(MTS)以及肖特基模块等。

二极管模块的工作原理
二极管实物晶体二极管为一个由p型半导体和n型半导体形成的pn结,在其界面处两侧形成空间电荷层,并建有自建电场。当不存在外加电压时,由于pn结两边载流子浓度差引起的扩散电流和自建电场引起的漂移电流相等而处于电平衡状态。当外界有正向电压偏置时,外界电场和自建电场的互相抑消作用使载流子的扩散电流增加引起了正向电流。当外界有反向电压偏置时,外界电场和自建电场进一步加强,形成在一定反向电压范围内与反向偏置电压值无关的反向饱和电流I0。当外加的反向电压高到一定程度时,pn结空间电荷层中的电场强度达到临界值产生载流子的倍增过程,产生大量电子空穴对,产生了数值很大的反向击穿电流,称为二极管的击穿现象。pn结的反向击穿有齐纳击穿和雪崩击穿之分。
