The thyristor module has a wide range of applications in the fields of temperature control, dimming, excitation, electroplating, charging and discharging, electric welding machines, plasma arcing, etc. It can play a role in adjusting and transforming the size of power energy. It is used in industry and communication. , Military industry and other occasions are very useful, but in practical applications, there are still people who do not particularly understand the SCR module. Today, the editor will briefly introduce the main parameters of the SCR module.

The main parameters of the SCR module:

(1) Rated average on-state current IT Under certain conditions, the average value of the 50 Hz sine half-wave current that can pass continuously between the anode and the cathode.

(2) Reverse cathodic cut-off peak voltage VPR When the SCR is in reverse turn-off state with reverse voltage applied, the reverse peak voltage applied to both ends of the SCR can be repeated. When used, the parameter value given in the manual cannot be exceeded.

(3) Positive blocking peak voltage VPF When the control electrode is open without a trigger signal and the anode forward voltage has not exceeded the conduction voltage, the positive peak voltage applied to both ends of the thyristor can be repeated. The peak forward voltage of the thyristor must not exceed the parameter value given in the manual.

(4) To maintain the current IH at a specified temperature, the control electrode is open to maintain the anode forward current required for the thyristor to conduct.

(5) The control electrode trigger current Ig1 and the trigger voltage VGT are the required control electrode current and voltage when a certain voltage is applied between the anode and the cathode under the specified ambient temperature. .

I hope that the above introduction can enhance everyone's understanding of SCR modules. If you want to learn more about SCR modules, you can continue to pay attention to the content update on this site.
