The role of the thyristor Thyristor is an important power control device, which plays a key role in the field of electronics and power. Its main function is to control the current flow and realize the switch and regulation of power. The following are the main functions of thyristors: (1) Power switch control The thyristor can be used as a power switch to control the on-off of the circuit. When the control voltage of the thyristor reaches a certain level, it switches from the off state to the on state, allowing the current to pass through. This switching characteristic makes thyristors widely used in the distribution and control of power systems, such as controlling motors, electric furnaces, lamps and so on. (2) Current regulation and converter By controlling the trigger Angle of the thyristor, the current in the circuit can be adjusted to achieve accurate current regulation. This is useful in applications where precise current control is required, such as resistance heating, AC motor speed regulation, and so on. (3) AC-DC conversion Thyristors can convert alternating current to direct current, which is useful in some specific applications, such as DC motor drive, DC power acquisition, etc. (4) Voltage control The thyristor can also be used to control the voltage of the circuit, and the voltage waveform can be adjusted by controlling the trigger Angle of the thyristor. (5) Power factor correction Thyristors can be used to improve the power factor of power systems. By controlling the conduction Angle of the thyristor, a certain harmonic current can be generated in the circuit to improve the power factor of the system. Power stability improvement: In power systems, thyristors can be used to adjust voltage and current, thereby improving the stability of the power system and reducing voltage fluctuations and electrical surges in the power system.

Important parameters of thyristors Trigger current threshold (I_GT) : The trigger current threshold is the minimum current that needs to be applied to the gate to switch the thyristor from the off state to the on state. This parameter determines the minimum control current of the touch thyristor. Holding current (I_H) : Holding current refers to the minimum current that needs to flow through the thyristor in the on-state to keep it on-. If the current falls below the holding current, the thyristor will automatically shut off. Maximum rated voltage (V_RRM) : The maximum rated voltage is the maximum reverse repeat voltage that a thyristor can withstand. This parameter is related to the voltage tolerance of the thyristor and determines the voltage range of the circuit for which it is applicable. Maximum rated current (I_TAV) : The maximum rated current refers to the maximum average current that the thyristor can withstand. This parameter is related to the current bearing capacity of the thyristor and determines its applicable circuit power range. Package type and heat dissipation: Different thyristor package types and heat dissipation designs affect their thermal characteristics and durability. Proper packaging and thermal design can ensure that the thyristor does not overheat during operation. Trigger Angle (α) : The trigger Angle is the phase Angle of thyristor conduction, usually measured in alternating current cycles. By controlling the trigger Angle, the delayed conduction of the current can be realized and the current size can be adjusted. Switching speed: The switching speed is the switching time of the thyristor from off to on, and from on to off. The fast switching speed is suitable for high frequency applications, such as variable frequency speed control systems. Temperature characteristics: The performance of a thyristor is affected by temperature, so its temperature characteristics are an important parameter. Excessive temperature may cause performance degradation or damage.
