1, What is a voltage equalization resistor?
Equalizer resistor is a variable resistor commonly used in the voltage stabilization circuit of power supplies to achieve stable voltage output. The principle of voltage equalization resistor is to change the current in the circuit by adjusting the resistance value, so as to maintain stable output voltage. In circuits, the voltage equalizing resistor is usually combined with other components to form a voltage regulator circuit, which is used to maintain the stability of the power output.
2, How to choose the average voltage resistance value?
2.1. Choose according to the required voltage range
The resistance value of the voltage equalizing resistor determines the range of the output voltage of the voltage regulator, so the selection of the value of the voltage equalizing resistor needs to be based on the required voltage range. Generally speaking, the resistance of a voltage equalizing resistor should be slightly lower than half of the required output voltage.
2.2. Choose based on the maximum output current
The rated power of a voltage equalizing resistor determines its maximum operating current, so the selection of a voltage equalizing resistor needs to be based on the actual load of the circuit. The rated power of the voltage equalizing resistor should be selected based on the load current to ensure its stable and reliable operation.
2.3. Choose based on stability requirements
The quality of the equalizing resistor has a significant impact on the stability of the voltage regulator, so its quality also needs to be considered when selecting the equalizing resistor. Generally speaking, choosing resistors with good quality, low temperature coefficient, and high linearity can achieve better stability. In addition, the temperature variation of the equalizing resistor can also affect the stability of the voltage regulator, so an appropriate temperature coefficient should be selected according to the actual situation.
In short, when choosing a voltage equalizing resistor, it should be reasonably selected according to the actual situation, and the resistance value, rated power, and quality of the voltage equalizing resistor should be set reasonably to ensure the stability and reliability of the circuit.
1. Do not use a low resistance value of the voltage equalizing resistor, otherwise it will cause unstable output voltage or inability to output.
2.In practical applications, reasonable heat dissipation design should be carried out for the voltage equalizing resistor to ensure its normal operation.
3.When choosing a voltage equalization resistor, products with high precision, stability, and quality should be selected to improve the reliability and stability of the circuit.
4. Pay attention to the installation direction of the voltage equalizing resistor in the circuit, which should be installed correctly to ensure its normal operation.
