Silicon Controlled Rectifier (SCR) is a kind of high-power electrical component, also known as thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driving device to realize the control of high-power equipment with low-power control. It has been widely used in AC and DC motor speed control system, power regulation system and servo system.
Thyristors are divided into two kinds: unidirectional thyristors and bidirectional thyristors. Bidirectional thyristor is also called TRIAC, or TRIAC for short. The bidirectional thyristor is structurally equivalent to two unidirectional thyristors in reverse connection, and this thyristor has a dual pilot pass function. The on-off state is determined by the control pole G. Adding a positive pulse (or negative pulse) to the control pole G. can make it forward (or reverse) conduction. The advantage of this device is that the control circuit is simple and there is no reverse voltage problem, so it is particularly suitable for AC contactless switch use.
