FAQ about Thyristors - SCRs
-
1. What is the difference between thyristor and SCR?
Thyristor and thyristor (SCR) are actually the same device, just with different names.
Basic concepts and definitions
Thyristor, also known as silicon controlled rectifier (SCR), is a high-power electrical component with the advantages of small size, high efficiency and long life. It usually consists of three electrodes: anode (A), cathode (K) and gate (G). Thyristors are divided into unidirectional thyristors and bidirectional thyristors. Unidirectional thyristors can be triggered to turn on by applying a positive pulse to the control electrode G, while bidirectional thyristors (TRIAC) can be turned on by applying a positive or negative pulse to the control electrode G. -
2. What are the uses of SCR?
The main uses of SCR (silicon controlled rectifier) include the following aspects:
Power switch application: SCR is suitable for medium and high voltage AC power control applications, such as lighting adjustment, voltage regulator and motor control. It can control high-power devices at high voltage and trigger the opening and closing of devices through the control terminal (gate), which is suitable for occasions that require frequent switching.
Automatic control system: SCR is a high-power driving device in the automatic control system, which can realize the control of high-power equipment with low-power controls. It is widely used in AC and DC motor speed control systems, power control systems and follow-up systems.
Selective catalytic reduction system: In the automotive field, SCR refers to the selective catalytic reduction system, which is used to reduce NOx in engine exhaust to meet higher emission regulations.
Circuit protection: In some cases, SCRs may be formed unintentionally in integrated circuits. When they are triggered, they may cause circuit failures, even reliability problems and damage. Therefore, this situation needs to be avoided when designing circuits.

3. Is SCR a DC switch or an AC switch?
AC switch
SCR (Silicon Controlled) is mainly used for AC switching. SCR, or thyristor, is a high-power semiconductor device, mainly used in phase control, rectification, voltage regulation, contactless switching and other applications in AC circuits.
Working principle of SCR
SCR is a four-layer, three-terminal PNPN structure semiconductor device, composed of alternating P-type and N-type semiconductor materials, forming three main terminals: anode, cathode and gate. In the absence of a gate trigger signal, SCR behaves as a reverse-biased PN junction, and even if there is a voltage between the anode and cathode, SCR will not conduct. When the gate receives a sufficiently large trigger signal, the SCR will change from the cut-off state to the on state.
