ABB 5SHX2645L0006可控硅模块是一种以可控硅（晶闸管）为基础、根据电路要求组装成的独立完整的可控整流单元，它与主电路接口完全配套、容易安装、维修方便。可控硅模块按功能结构划分通常包含阳极、阴极、控制极和电路接口等单元。

可控硅的工作原理是：可控硅是由两个PN结加正向电压而形成的PNP型半导体器件，其工作过程是将输入的直流电压变为控制信号，然后驱动可控硅导通和关断。在电流的控制下，使被控制电路中的交流功率开关元件按预定方向动作。当接通或切断一定数量的电流后，由于PN结正向导通的交替变化而产生热量而使温度升高。同时由于漏源极之间存在一定的电阻值，因此会产生一定的反向电动势将多余的电能消耗掉。最后通过调节触发角的大小就可以达到对负载进行调制的目的。

可控硅的特性有以下几点：

伏安特性：单向导通的I-V特性曲线是直线形的。

输入阻抗：对直流而言，它的输入电阻较大。

输出阻抗：一般小于50Ω。

击穿场强：（Kv）大于2000Vm。

饱和压降：（Usr）小于1kV。

温度系数小，（Tgδt）：10-6~10-7。

耐过电压能力差。

频率特性好。

无噪声。

寿命长。

ABB 5SHX2645L0006 thyristor module is an independent and complete controllable rectifier unit based on thyristor (thyristor) and assembled according to circuit requirements. It is fully compatible with the main circuit interface, easy to install and easy to maintain. Thyristor module according to the functional structure of the division usually includes anode, cathode, control pole and circuit interface and other units.

The working principle of thyristor is: thyristor is a PNP type semiconductor device formed by two PN junctions plus a forward voltage, and its working process is to change the input DC voltage into a control signal, and then drive the thyristor on and off. Under the control of current, the AC power switch element in the controlled circuit acts in a predetermined direction. When a certain amount of current is switched on or off, the temperature increases due to the heat generated by the alternating change of the PN junction positive channel. At the same time, because there is a certain resistance value between the drain and source, a certain reverse electromotive force will be generated to consume the excess electrical energy. Finally, the load can be modulated by adjusting the size of the trigger Angle.

The characteristics of thyristor are as follows:

Volt-ampere characteristics: The I-V characteristic curve of a single pass is linear.

Input impedance: For DC, its input resistance is larger.

Output impedance: generally less than 50Ω.

Breakdown field strength: (Kv) greater than 2000Vm.

Saturation voltage drop: (Usr) less than 1kV.

The temperature coefficient is small, (Tgδt) : 10-6~10-7.

Poor resistance to overvoltage.

Good frequency characteristics.

No noise.

Long life.
