Too high or too low output voltage is not good. Today, let's ta58.8 v lithium battery chargerlk about how to deal with the common problems of too low output voltage. What problems will low output voltage cause?
But the overall system software can't work normally. Take the examples commonly used in people's daily life. Well, when the voltage is too low, the light bulb doesn't light or dark, which really doesn't consider people's requirements.
If the voltage is too low for a long time, it will greatly reduce the service life of the power circuit. How should people deal with this problem?
The fourth key index value of the alternator charging lithium battery is the precision of the output voltage. Some technical engineers gave feedback at the time of testing the precision of the power supply voltage. The output voltage was slightly lower and could not consider the precision provisions obtained in the technical guide. What was the cause? Was it the error of the test standard or the poor quality of the product itself?
Usually, it can be carried out according to the exclusion method. First assume that the goods are good, and carry out the test according to the test method given by the manufacturer. If there are still problems, you can basically distinguish them from the poor goods.
First, people will analyze what causes the output voltage to be too low, so that it can be treated symptomatically.
1. The input voltage is low or the output power is not enough.
2. The output line is too long or too thin, resulting in excessive line loss.
3. The pressure drop of anti reverse connection secondary pipe at the input end is too large.
4. The input filter inductance is too large.
For several reasons, how should people deal with it? Let's discuss the way.
Increase the voltage or switch to a higher power supply; Adjust the routing, expand the cross-sectional area of the conductor or reduce the length of the transmission line to reduce the internal resistance; Switch to the secondary pipe with small conduction pressure drop; Reduce the filter inductance or reduce the internal resistance of the inductor.
