5SGY3545L0017可控硅有源整流器是一種半導體電子器件，由至少三個PN結(即P型半導體和N型半導體的結合物)組成。它具有單向導電性和可控的關斷特性，可以將交流電壓轉換為直流電壓。這種整流器具有效率高、無機械噪聲和磨損、響應速度快、體積小、重量輕等諸多優(yōu)點。
二、工作原理
5SGY3545L0017 可控硅整流器的工作原理基于晶閘管的特性。在正向阻斷狀態(tài)下，如果給予控制極一低功率的觸發(fā)信號(使控制極-陰極PN結導通)，則器件可迅速被激發(fā)到導通狀態(tài)，之后毋須繼續(xù)保持觸發(fā)電流即可維持在通導狀態(tài)。此時，如果電流降至維持電流以下，器件可恢復到阻斷狀態(tài)。這種特性使得可控硅整流器能夠實現(xiàn)對電功率的精確控制。

The 5SGY3545L0017 thyristor active rectifier is a semiconductor electronic device consisting of at least three PN junctions (i.e. a combination of P-type semiconductors and N-type semiconductors). It has unidirectional conductivity and controllable turn-off characteristics, and can convert AC voltage to DC voltage. The rectifier has many advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size and light weight.
Second, the working principle
The working principle of the 5SGY3545L0017 thyristor rectifier is based on the characteristics of the thyristor. In the forward blocking state, if a low-power trigger signal is given to the control pole (so that the control-cathode PN junction is switched on), the device can be quickly excited to the on-state, and then it can be maintained in the on-state without continuing to maintain the trigger current. At this point, if the current drops below the maintenance current, the device can return to the blocked state. This characteristic enables the thyristor rectifier to achieve precise control of electrical power.
