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BGBG2完全导通。实际这一是“一触即发”的，对可控硅来说，触发加入控制极，可控硅立即导通。导通的时间主要决定于可控硅的性能。可控硅一经触发导通后，由于循环反馈的原因，流入BG1基极的电流已不只是初始的Ib1，而是经过BGBG2放大后的电流（β1*β2*Ib1）这一电流远大于Ib1，足以保持BG1的导通。此时触发即使消失，可控硅仍保持导通状态只有断开电源Ea或Ea，使BGBG2中的集电极电流小于维持导通的值时。中文名电流互感器外文名Currenttransformer简称CT所属领域能源、
