苏州创芯奇半导体有限公司电压测方法可控硅为什么其有“以小控大”的可控性呢？下面我们用图表-27来简单分析可控硅的工作原理。首先，可以把从阴极向上数的***、二、三层看面是一只NPN型号晶体管，而二、三四层组成另一只PNP型晶体管。其中第二、第三层为两管交迭共用。当在阳极和阴极之间加上一个，又在控制极G和之间（相当BG1的基一射间）输入一个正的触发信号，BG1将产生电流Ib1，经放大，BG1将有一个放大了β1倍的电流IC1。因为BG1集电极与BG2基极相连，IC1又是BG2的基极电流Ib2。BG2又把比Ib2（Ib1）放大了β2的集电极电流IC2送回BG1的基极放大。如此循环放大，直到BG1、BG2完全导通。实际这一过程是“一触即发”的过程，对可控硅来说，触发信号加入，可控硅立即导通。导通的时间主要决定于可控硅的性能。优势代理产品为大功率平板式晶闸管、可控硅、二极管、IGBT，品牌如EUPEC、西门康、西码、三菱、ABB、三社、IR、明纬开关电源等国外功率模块。在国内严格按照国际标准生产：ZP型普通整流管、ZK型快速整流管、KP型普通晶闸管、KS型双向晶闸管、KK型快速晶闸管、KG型高频晶闸管、桥式整流器、电力模块、肖特基模块、SF超快***二极管、电焊机专用模块、固态继电器、固态调压器、型材散热器等电力半导体器件。本公司坚持以‘诚信为本、质量首位、价格合理’的经营理念期待与贵公司的合作，一步一个脚印，做大做强，再创辉煌！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​N540SH02N540SH04N540SH06N540SH08N540SH10N540SH12N540SH14N540SH16N540SH18N600SH02N600SH04N600SH06N600SH08N600SH10N600SH12N600SH14N600SH15N560SH36N560SH38N560SH40N560SH42N560SH44N560SH45N630SH26N630SH28N630SH30N630SH32N630SH34N630SH36N640SH20N640SH22N640SH24N640SH26N640SH28N640SH30N760SH02N760SH04N760SH06N760SH08N760SH10N760SH12N760SH14N760SH16N760SH18N760SH20N990SH02N990SH04N990SH06N990SH08N990SH10N990SH12N990SH14N990SH16N750SH26N750SH28N750SH30N750SH32N750SH34)
