　　5SGY3545L0017可控硅有源整流器是一种半导体电子器件，由至少三个PN结(即P型半导体和N型半导体的结合物)组成。它具有单向导电性和可控的关断特性，可以将交流电压转换为直流电压。这种整流器具有效率高、无机械噪声和磨损、响应速度快、体积小、重量轻等诸多优点。

　　二、工作原理

　　5SGY3545L0017 可控硅整流器的工作原理基于晶闸管的特性。在正向阻断状态下，如果给予控制极一低功率的触发信号(使控制极-阴极PN结导通)，则器件可迅速被激发到导通状态，之后毋须继续保持触发电流即可维持在通导状态。此时，如果电流降至维持电流以下，器件可恢复到阻断状态。这种特性使得可控硅整流器能够实现对电功率的精确控制。

　　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.
