晶閘管模塊是一種大功率半導(dǎo)體元器件，不僅有單向?qū)щ姷恼髯饔?，又有可以控制的開關(guān)作用，可以用微小的功率控制較大的功率。晶閘管模塊又被稱為可控硅，其工作條件為：

如果它承受反向陽極的電壓的時(shí)候，無論門極承受一樣的電壓，都會(huì)處于一個(gè)反向阻斷的一個(gè)狀態(tài)。
當(dāng)它承受正極電壓時(shí)，只有在柵極低于正向電壓時(shí)才會(huì)導(dǎo)通。此時(shí)，晶閘管處于正導(dǎo)通狀態(tài)。
只要有一定的正極電壓，不管柵極電壓如何，都保持導(dǎo)通狀態(tài)，即使導(dǎo)通后，閘極將失去功能。大門只起到觸發(fā)作用。
當(dāng)接通時(shí)，當(dāng)主電路的電壓（或電流）降至接近零時(shí)，晶閘管模塊將會(huì)關(guān)閉。

5SHY3545L0014 is an ABB thyristor module.
A thyristor (also known as a thyristor) is a semiconductor device used to control the flow of electrical current.

It has extremely high reliability and stability, and can be applied to various industrial control and regulation systems, such as power, manufacturing and automation control. Its design focuses on easy to master, convenient operation and rich built-in integration functions, which can meet the needs of various application scenarios. At the same time, it also has real-time characteristics and strong communication capabilities, which can carry out fast and stable data transmission with other devices. In addition, it also supports a variety of extension modules, which can meet the needs of different users and achieve more functions

The function of thyristor module is to stabilize voltage and current.
Thyristor module is a kind of high-power semiconductor component, which not only has unidirectional conductive rectification function, but also has controllable switching function, which can control large power with small power. Thyristor module is also known as thyristor, its working conditions are:

If it is subjected to the voltage of the reverse anode, no matter the gate is subjected to the same voltage, it will be in a state of reverse blocking.
When it is subjected to a positive voltage, it will only be switched on if the gate is lower than the forward voltage. At this time, the thyristor is in a positive conduction state.
As long as there is a certain positive voltage, regardless of the gate voltage, it remains on, even if the gate will lose its function after it is on. The gate only acts as a trigger.
When switched on, the thyristor module will shut down when the voltage (or current) of the main circuit drops to near zero.
