How to choose thyristor?

release time:2022-03-17Author source:SlkorBrowse:1020

What exactly is a SCR? In fact, this kind of thyristor is divided into one-way and two-way, so we usually find that the over-current and over-voltage protection of color TVs use one-way thyristor, but in some regulating circuits and power control All are triacs. Then a feature of the thyristor is that it can replace the AC switch because of its own advantages, and can play a very good effect in the control circuit. When selecting, it can be selected according to its various parameters.

SCR

SCR can also be called a rectifier, because this kind of thing is light in weight and not large in size, the key is to control more convenient, such a switch-controlled conversion occasion, it can be said The effect is very good, and the voltage control of each anode and cathode can play a very important effect. After all, whether it is to turn on or off these voltages and currents for control can play a very good role. In the face of the use of this kind of non-contact switch, many people will also find that this kind of switch without contact is really very advantageous to use, and the effect of this use in many circuit controls is still very obvious and ineffective. There is a phenomenon of poor contact or burning. From this point, it can be understood that this electronic component is still very good in circuit use.
SCR Due to its own advantages, we can see that the use of various circuits is still very obvious, but in the selection. Its parameters are the reverse blocking peak voltage and the rated average current. Through these parameters, it can play a very good effect in the use of the computer, and even control the current on and off to achieve a better effect. And most people will find that there are too many types when faced with this choice, and they don't know how to use it, because the three unidirectional thyristors are basically different in sensitivity, so special attention should be paid to the choice. , after all, if you know more about the effect of use in the circuit, you can naturally have more choices, and you will choose better.
