5SHY3545L0001 IGCT可控硅主板

5SHY3545L0001 可控硅分单向可控硅和双向可控硅两种。双向可控硅也叫三端双向可控硅，简称TRIAC。双向可控硅在结构上相当于两个单向可控硅反向连接，这种可控硅具有双向导通功能。其通断状态由控制极G决定。在控制极G上加正脉冲(或负脉冲)可使其正向(或反向)导通。

5SHY3545L0001 Thyristors are divided into two types: unidirectional thyristors and bi-directional thyristors. Bidirectional thyristors are also called triacs, or TRIACs for short. bi-directional thyristors are structurally equivalent to two unidirectional thyristors connected in reverse, and this type of thyristor has a bi-directional conduction function. The on/off state is determined by the control pole G. A positive pulse is applied to the control pole G. In the control pole G plus a positive pulse (or negative pulse) can make its positive (or reverse) conduction.

5SHY3545L0001 在材料上，以硅单晶为基本材料P1N1P2N2四层三端器件.半导体器件。因为它的特性类似干直空闸流管，所以国际上通称为硅晶体闸流管,简称晶闸管,又因为晶闸管一开始的在静止整流方面，所以又被称之为硅可控整流元件，简称为可控硅SCR。

5SHX0360D0001 In terms of material, silicon single crystal is used as the basic material P1N1P2N2 four-layer three-terminal device . Semiconductor devices. Because of its characteristics similar to the dry straight empty gate current tube, so the international commonly known as silicon crystal gate current tube, referred to as thyristor, and because the thyristor at the beginning of the static rectifier, so it is also known as silicon controllable rectifier components, referred to as silicon controlled SCR.

5SHX0360D0001可控硅简称SCR，是一种大功率电器元件，也称晶闸管。它具有体积小、效率高、寿命长等优点，在自动控制系统中，可作为大功率驱动器件，实现用小功率控件控制大功率设备，它在交直流电机调速系统、调功系统及随动系统中得到了广泛的应用。

5SHX0360D0001 Thyristor abbreviation SCR, is a high-power electrical components, also known as thyristor. It has the advantages of small size, high efficiency, long life, etc. In the automatic control system, it can be used as a high-power drive device to achieve the control of high-power equipment with small power controls, which is widely used in the AC and DC motor speed control system, power control system and follower system.
