A thyristor module is a semiconductor electronic device commonly used in power control and power regulation applications. It is also often referred to as a thyristor switch, Silicon Controlled Rectifier, or simply SCR(Silicon Controlled Rectifier). Here are some basic information about thyristor modules:
1. Principle: The thyristor module works based on the characteristics of semiconductor silicon materials. It can control the current flow by turning it on or off under the pulse signal of the control voltage
Voltage and current control.
2. Application: SCR modules are widely used in power control, power regulation, lighting control, heating control, motor control, AC power control and various industrial automation applications.
3 Features: The thyristor module has the advantages of fast response time, current bearing capacity, efficiency and low maintenance cost. They can be used for high current and pressure applications.
4. Control mode: The thyristor module can be controlled by pulse width modulation (PWM) or pulse frequency modulation (PFM) to achieve accurate voltage and current control.
5. Protection: In the use of thyristor modules, it is usually necessary to consider safety measures such as overheat protection, overcurrent protection and overvoltage protection to ensure the safety and reliability of the equipment.
Thyristor module is a power semiconductor device in the form of module package, which has a four-layer structure of three PN junctions. It usually consists of two diodes that, when the input current exceeds the rated value, produce a voltage drop under the resistance of the synchronous reactor, thus limiting the AC current through. When the DC voltage reaches a certain value, the pulse voltage or pulse waveform is output under the control of the inverter bridge.
In addition, the thyristor module has soft start and soft off functions, and adopts multi-channel MOSFETs as power switching devices to achieve pwm control to obtain higher conversion efficiency and faster response speed. It also uses high-speed digital signal processor dsp to control the whole device more intelligent and higher degree of automation.
There are many types of thyristor modules, as follows:
According to the structure and packaging process, thyristor modules can be divided into plate type and round shell type.
According to different packaging forms, thyristor modules can be divided into metal packaging thyristor, plastic packaging thyristor and ceramic packaging thyristor, of which metal packaging thyristor is divided into bolt shape, plate shape, round shell shape.
According to different current capacity, thyristor modules can be divided into high-power thyristor, medium-power thyristor and low-power thyristor.
According to the pin and polarity, the thyristor module can be divided into two pole thyristor, three pole thyristor and four pole thyristor.
According to the disconnection speed, the thyristor module can be divided into ordinary thyristor and high-frequency (fast) thyristor.
Depending on the use, Thyristor modules can be divided into ordinary thyristor modules (MTC, MTX, MTK, MTA), ordinary rectifier module (MDC), ordinary thyristor, rectifier mixed module (MFC), fast thyristor, rectifier and mixed module (MKC, MZC), non-insulated thyristor, rectifier and mixed module (commonly referred to as welding machine special module MT G, MDG), three-phase rectifier bridge output thyristor module (MDS), single-phase (three-phase) rectifier bridge module (MDQ), single-phase half-controlled bridge (three-phase fully controlled bridge) module (MTS) and Schottky module.
