Correct connection of varistors
Varistor is a kind of component widely used in electronic equipment. It has the characteristics of high sensitivity and fast response speed. In order to ensure the stability of the varistor and make it work properly, the correct connection is very important. This paper will introduce the correct connection method of varistor and its application in electronic circuit in detail.
First, the basic principle of varistor
Varistor is a kind of component based on nonlinear resistance effect. When the applied voltage exceeds a certain value, its resistance value will mutate, producing a switch similar to the effect. This is because the varistor contains semiconductor materials such as zinc oxide, and when the voltage is increased, the holes and electrons in these materials will be excited, increasing the resistance value.
Two, the correct connection of varistor
The correct connection has a crucial effect on the stability and response speed of varistor. In general, the varistor should be connected to the power supply in series. The specific connection method is as follows:
1. On the circuit board added to the varistor, find the interface of the parts or components that need to be protected (such as LED lights, etc.).
2. Connect the two pins of the varistor to the positive and negative poles of the protection components respectively.
3, connect the positive terminal of the power supply to the other end of the varistor, and connect the negative terminal of the power supply to the negative terminal of the component.
4. Add overvoltage protection components on the circuit board.
5. Connect the entire circuit board to the power supply.
Through the above correct connection, the varistor can automatically cut off the circuit when the power supply voltage is too high, protecting other components from damage.
Third, the application of varistor in electronic circuits
In addition to overvoltage protection, varistors have the following applications in electronic devices:
1, as a buck component. When the voltage of the circuit board is too high, it can be reduced to a safe range through the cutting action of the varistor.
2, as a filter component. In the noisy environment, the varistor can effectively filter out the interference signal and improve the working stability of the whole circuit.
3, as a leak protection component. Connecting the varistor in parallel with the capacitor can effectively protect the capacitor from being damaged by overcurrent.
Iv. Conclusion
The correct application of varistor can effectively prevent the damage of circuit components and improve the stability of the entire circuit. This paper introduces the correct connection method of varistor and its application in electronic circuit in detail, hoping to be helpful to readers.
